This fixes a runtime error triggered when calling `invokeRpc`:
```
type 'Future<dynamic>' is not a subtype of type 'Future<Map<String, dynamic>>'
```
Also adds a log message for why connections are failing, as well as a
default timeout when attempting to connect to a websocket.
This change adds Dart VM event support (listening for when a VM starts/stops by using a periodic heartbeat).
This also adds support to connect to a specific `IsolateRef` through the flutter driver, so that when an application spawns, it can immediately be driven (as shown in included example code).
When forwarding all ports, run a test connection to each Dart VM instance, stopping port forwarding if the connection fails.
Also does the same for any batched calls that hit all Dart VM instances.
* Handle error count reported by frontend.
Extend compilation result from single string to a structure(string filename and integer error count).
* Use ?.
* Include engine roll with dart sdk roll.
* parse(onError) -> tryParse
* Make '?? throw' more readable and avoid issue with analyzer
* Fix test so it mocks compiler output including errors count
* Revert "Revert "Move mockito to 3.0.0-alpha. (#15949)" (#15979)"
This reverts commit e59651f925.
* More thenReturn to thenAnswer when mocking Futures
* Revert "More thenReturn to thenAnswer when mocking Futures"
This reverts commit 194d2cf417 as we are reverting engine roll.
* Revert "Revert "More thenReturn to thenAnswer when mocking Futures""
This reverts commit 52c9e96b30.
* Add dependency override
* Fix issue
* Move mockito to 3.0.0-alpha.
This is needed so it matches mockito version used internally.
* Pick up +2 for the fixes
* Fix whenReturn in fuchsia_remote_debug_protocol
* more thenReturn becomes thenAnswer
* more thenReturn becomes thenAnswer
* more thenReturn becomes thenAnswer
Adds a package that will support connecting to and debugging devices with multiple instances of the Dart VM, and operate on multiple Isolates and Flutter Views.
Currently supports connecting to all existing Dart VMs and extracting information about all Flutter Views running across each VM.
