Danny Tuppeny 2ff94f8882 [analysis_server] Allow action in response to showMessageRequest to be null
This allows for users to dismiss a notification without taking any action (something that VS Code / LSP allows for but this API did not).

<h1>Analysis Server API Specification</h1>
<h1 style="color:#999999">Version
1.34.0
</h1>
<p>
This document contains a specification of the API provided by the
analysis server. The API in this document is currently under
development. Changes to the API will be accompanied by an update to the
protocol version number according to the principles of semantic
versioning (<a href="https://semver.org/">semver.org</a>).
</p>
<h2>Overview</h2>
<p>
The analysis server API is a bi-directional client-server
API. The API is independent of the transport mechanism used, but
is heavily influenced by a model in which sockets or character
streams are used to transport JSON-RPC encoded information.
</p>
<h3>Transport Mechanism</h3>
<p>
The characters passed to the server are expected to be encoded
using UTF-8.
</p>
<p>
When character streams are used as the transport, messages are
delineated by newlines. This means, in particular, that the JSON
encoding process must not introduce newlines within a
message. Note however that newlines are used in this document
for readability.
</p>
<p>
It is the client's responsibility to read output from the server to
avoid its blocking.
</p>
<p>
To ease interoperability with Lisp-based clients (which may not
be able to easily distinguish between empty lists, empty maps,
and null), client-to-server communication is allowed to replace
any instance of "<tt>{}</tt>" or "<tt>[]</tt>" with null. The
server will always properly represent empty lists as
"<tt>[]</tt>" and empty maps as "<tt>{}</tt>".
</p>
<h3>Communication Structure</h3>
<p>
Clients can make a request of the server and the server will
provide a response for each request that it receives. While many
of the requests that can be made by a client are informational
in nature, we have chosen to always return a response so that
clients can know whether the request was received and was
correct.
</p>
<p>
There is no guarantee concerning the order in which responses
will be returned, but there is a guarantee that the server will
process requests in the order in which they are sent as long as
the transport mechanism also makes this guarantee. Responses can
be returned in an order that is different from the order in
which the requests were received because some requests take
longer to process than others.
</p>
<p>
Every request is required to have two fields and may have two
additional optional fields. The first required field is the 'id'
field, which is only used by the server to associate a response
with the request that generated the response. The second
required field is the 'method' field, which is used to determine
what the server is being requested to do. One optional field is
the 'params' field, whose structure is dependent on the method
being requested. The structure of this field is described with
each request for which it is required. The other optional field
is the 'clientRequestTime' field, which is a number indicating
the time at which the client made the request (milliseconds
since epoch). Providing clientRequestTime helps us track
how responsive analysis server is to client requests
and better address any issues that occur.
</p>
<p>
Every response has up to three fields. The first field is the
'id' field, which is always present and whose value is the
identifier that was passed to the request that generated the
response. The second field is the 'error' field, which is only
present if an error was encountered while processing the
request. The third field is the 'result' field, whose structure
is dependent on the method being responded to, and is described
with each request that will produce it.
</p>
<p>
The server can communicate to the clients by sending a
notification. The purpose of these notifications is to provide
information to clients as it becomes available rather than to
require that clients poll for it. Unless explicitly stated, all
notifications are designed to return the complete information
available at the time the notification is sent; clients are not
required to update previously communicated
results. Consequently, the server can and should return partial
results before all results are available. For example, the
syntactic errors for a file can be returned as soon as the
syntactic analysis is complete, and both syntactic and semantic
errors can be returned together at a later time.
</p>
<p>
Each notification has two fields. The first field is the 'event'
field, which identifies the kind of notification. The second
field is the 'params' field, whose structure is dependent on the
kind of notification being sent. The structure of this field is
described with each notification.
</p>
<p>
The server can also communicate to the clients by sending a request. As with
requests sent from the client, requests from the server have both an 'id' and
a 'method' field, and an optional 'params' field. The ids used by the server
are independent of the ids used by the client. In other words, the ids sent by
the server might be equal to ids already sent from the client, but are
unrelated to the client request with that same id.
</p>
<p>
In order to be backward compatible, clients should ignore fields that were
not specified in the version of the API on which they were based. Clients
should also use the server.getVersion request to test that the version of
the server supports an API before using it.
</p>
<h3>Eventual Consistency</h3>
<p>
The analysis server satisfies requests under the principle of
<a href="https://en.wikipedia.org/wiki/Eventual_consistency">eventual
consistency</a>.
That is, in some cases it may return responses with the currently available
results while it's catching up with unprocessed changes.
</p>
<h3>Enumerations</h3>
<p>
Responses from the server may include enumerations indicating the kind of a
specific item. The enums may be extended with new values in future versions of
the server so clients should ensure unknown values are handled gracefully, either
ignoring the item or treating it with some default/fallback handling.
</p>
<h3>Changelog</h3>
<h4>1.34.0</h4>
<ul>
<li>
Added the ability for the server to send requests to the client when the
client uses <tt>setClientCapabilities</tt> to enable the requests. Also
added the <tt>openUrlRequest</tt> and <tt>showMessageRequest</tt> requests.
</li>
</ul>
<h4>1.33.1</h4>
<ul>
<li><tt>SourceChange</tt> now has an optional <tt>selectionLength</tt> that may be
provided when <tt>selection</tt> is.</li>
</ul>
<h4>1.33.0</h4>
<ul>
<li>Requests <tt>getSuggestions2</tt> and <tt>getSuggestionDetails2</tt>
are enabled.</li>
</ul>
<h4>1.32.10</h4>
<ul>
<li>The <tt>MOVE_FILE</tt> refactor now supports moving/renaming folders.</li>
</ul>
<h4>1.32.8</h4>
<ul>

<li>Added optional <tt>replacementOffset</tt> and <tt>replacementLength</tt> on
<tt>CompletionSuggestion</tt> to support different per-completion text replacement
ranges (for example when inserting names for arguments, a different range may be
supplied than for completions that are not name labels).</li>
</ul>
<h4>1.32.4</h4>
<ul>
<li>Added <tt>ElementKind.TYPE_ALIAS</tt> and <tt>HighlightRegionType.TYPE_ALIAS</tt>
for non-function type aliases.</li>
</ul>
<h4>1.32.3</h4>
<ul>
<li>Removed the experimental <tt>completion.listTokenDetails</tt> request and
the associated data types.</li>
</ul>

</p>
<h4>Options</h4>
<blockquote>
<dl>
<dt>--client-id</dt>
<dd>
<p>
Specifies an identifier associated with the client. Used when
generating error reports.
</p>
<p>
Clients are strongly encouraged to provide this information in
order to improve the quality of information that can be provided
to them.
</p>
</dd>
</dl>
<dl>
<dt>--client-version</dt>

<p>
Clients are strongly encouraged to provide this information in
order to improve the quality of information that can be provided
to them.
</p>
</dd>
</dl>
<dl>
<dt class="deprecated">--no-error-notification</dt>
<dd>
<p><b>Deprecated:</b> clients should no longer pass this option in</p>
Disable notifications about errors (see analysis.error). If this
flag is not specified then notifications will be sent for all
errors produced for all files in the actual analysis roots.
</dd>
</dl>
<dl>
<dt class="deprecated">--no-index</dt>
<dd>
<p><b>Deprecated:</b> clients should no longer pass this option in</p>
This flag used to disable the server from generating an index, but now
it has no effect.
</dd>
</dl>
<dl>
<dt class="deprecated">--file-read-mode</dt>
<dd>
<p><b>Deprecated:</b> clients should no longer pass this option in</p>
An enumeration of the ways files can be read from disk. Some clients
normalize end of line characters which would make the file offset and
range information incorrect. The default option is <tt>as-is</tt>, but
can also be set to <tt>normalize-eol-always</tt>. The default option
(<tt>as-is</tt>) reads files as they are on disk. The
<tt>normalize-eol-always</tt> option does the following:
<ul>
<li>'\r\n' is converted to '\n';</li>
<li>'\r' by itself is converted to '\n';</li>
<li>this happens regardless of the OS editor is running on.</li>
</ul>
</dd>

The server will still always produce a response to the request
even in the case of cancellation, but clients should discard
any results of any cancelled request because they may be
incomplete or inaccurate.
This request always completes without error regardless of
whether the request is successfully cancelled.</p>

Return the errors associated with the given file. If the
errors for the given file have not yet been computed, or the
most recently computed errors for the given file are out of
date, then the response for this request will be delayed
until they have been computed. If some or all of the errors
for the file cannot be computed, then the subset of the
errors that can be computed will be returned and the
response will contain an error to indicate why the errors
could not be computed. If the content of the file changes after this
request was received but before a response could be sent, then an
error of type <tt>CONTENT_MODIFIED</tt> will be generated.

Return the navigation information associated with the given region of

<p>
Sets the root paths used to determine which files to analyze. The set
of files to be analyzed are all of the files in one of the root paths
that are not either explicitly or implicitly excluded. A file is
explicitly excluded if it is in one of the excluded paths. A file is
implicitly excluded if it is in a subdirectory of one of the root
paths where the name of the subdirectory starts with a period (that
is, a hidden directory).
</p>
<p>
Note that this request determines the set of requested
analysis roots. The actual set of analysis roots at any
given time is the intersection of this set with the set of
files and directories actually present on the
filesystem. When the filesystem changes, the actual set of
analysis roots is automatically updated, but the set of
requested analysis roots is unchanged. This means that if
the client sets an analysis root before the root becomes
visible to server in the filesystem, there is no error; once
the server sees the root in the filesystem it will start
analyzing it. Similarly, server will stop analyzing files
that are removed from the file system but they will remain
in the set of requested roots.
</p>
<p>
If an included path represents a file, then server will look
in the directory containing the file for a pubspec.yaml
file. If none is found, then the parents of the directory
will be searched until such a file is found or the root of
the file system is reached. If such a file is found, it will
be used to resolve package: URI's within the file.
</p>
<h4>parameters:</h4><dl><dt class="field"><b>included: List&lt;<a href="#type_FilePath">FilePath</a>&gt;</b></dt><dd>
<p>
A list of the files and directories that should be
analyzed.
</p>
</dd><dt class="field"><b>excluded: List&lt;<a href="#type_FilePath">FilePath</a>&gt;</b></dt><dd>
<p>
A list of the files and directories within the
included directories that should not be analyzed.

<p>
A mapping from source directories to package roots
that should override the normal package: URI resolution
mechanism.
</p>
<p>
If a package root is a file, then the analyzer
will behave as though that file is a
".dart_tool/package_config.json" file in the
source directory. The effect is the same as specifying the file
as a "--packages" parameter to the Dart VM when
executing any Dart file inside the source directory.
</p>
<p>
Files in any directories that are not overridden by this
mapping have their package: URI's resolved using the
normal pubspec.yaml mechanism. If this field is absent,
or the empty map is specified, that indicates that the
normal pubspec.yaml mechanism should always be used.

<p>
Set the priority files to the files in the given list. A
priority file is a file that is given priority when
scheduling which analysis work to do first. The list
typically contains those files that are visible to the user
and those for which analysis results will have the biggest
impact on the user experience. The order of the files within
the list is significant: the first file will be given higher
priority than the second, the second higher priority than
the third, and so on.

<p>
Note that this request determines the set of requested

<p>
Note that this request determines the set of requested
subscriptions. The actual set of subscriptions at any given
time is the intersection of this set with the set of files
currently subject to analysis. The files currently subject
to analysis are the set of files contained within an actual
analysis root but not excluded, plus all of the files
transitively reachable from those files via import, export
and part directives. (See analysis.setAnalysisRoots for an
explanation of how the actual analysis roots are
determined.) When the actual analysis roots change, the
actual set of subscriptions is automatically updated, but
the set of requested subscriptions is unchanged.

<p>
Request completion suggestions for the given runtime context.
</p>
<p>
It might take one or two requests of this type to get completion
suggestions. The first request should have only "code", "offset",
and "variables", but not "expressions". If there are sub-expressions that
can have different runtime types, and are considered to be safe to
evaluate at runtime (e.g. getters), so using their actual runtime types
can improve completion results, the server will not include the
"suggestions" field in the response, and instead will return the
"expressions" field. The client will use debug API to get current runtime
types for these sub-expressions and send another request, this time with
"expressions". If there are no interesting sub-expressions to get
runtime types for, or when the "expressions" field is provided by the
client, the server will return "suggestions" in the response.
</p>
<h4>parameters:</h4><dl><dt class="field"><b>code: String</b></dt><dd>

Subscribe for services that are specific to individual files.
All previous subscriptions are replaced by the current set of
subscriptions. If a given service is not included as a key in the map
then no files will be subscribed to the service, exactly as if the
service had been included in the map with an explicit empty list of
files.
</p>
<p>
Note that this request determines the set of requested
subscriptions. The actual set of subscriptions at any given
time is the intersection of this set with the set of files
currently subject to analysis. The files currently subject
to analysis are the set of files contained within an actual
analysis root but not excluded, plus all of the files
transitively reachable from those files via import, export
and part directives. (See analysis.setAnalysisRoots for an
explanation of how the actual analysis roots are
determined.) When the actual analysis roots change, the
actual set of subscriptions is automatically updated, but
the set of requested subscriptions is unchanged.

<p>
If a requested subscription is a directory it is ignored,
but remains in the set of requested subscriptions so that if
it later becomes a file it can be included in the set of
actual subscriptions.

parameters (e.g. getter), this field will not be defined. If the
element has zero parameters, this field will have a value of "()".
The value should not be treated as exact presentation of parameters,
it is just approximation of parameters to give the user general idea.
