Martin Kustermann 81df36216f Make utf8.encode() have Uint8List return type
Right now `utf8.encode()` has a static return type of `List<int>`
due to extending `Encoding` (which extends `Codec<String, List<int>>`).

We cannot easily change `Encoding` to extend `Codec<String, Uint8List>`
because that would also change `utf8.decode()` to require `Uint8List`
which would be a breaking change.

So instead we override `utf8.encode()` to have more precise return type.

Some parts of our SDK are run using the checked-in SDK, so it cannot
rely on the changed return type yet (until checked-in SDK is rolled).

So we use `const Utf8Encoder().convert()` as a temporary change, as
that already has `Uint8List` return type.

pub package package publisher

This package provides a library that performs static analysis of Dart code. It is useful for tool integration and embedding.

End-users should use the dart analyze command-line tool to analyze their Dart code.

Integrators that want to add Dart support to their editor should use the Dart Analysis Server. The Analysis Server API Specification is available. If you are adding Dart support to an editor or IDE, please let us know by emailing our list.

Configuring the analyzer

Both dart analyze and Dart Analysis Server can be configured with an analysis_options.yaml file (using an .analysis_options file is deprecated). This YAML file can control which files and paths are analyzed, which lints are applied, and more.

If you are embedding the analyzer library in your project, you are responsible for finding the analysis options file, parsing it, and configuring the analyzer.

The analysis options file should live at the root of your project (for example, next to your pubspec.yaml). Different embedders of analyzer, such as dart analyze or Dart Analysis Server, may choose to find the file in various different ways. Consult their documentation to learn more.

Here is an example file that instructs the analyzer to ignore two files:

analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
    - test/_data/p5/p5.dart
    - test/_data/bad*.dart
    - test/_brokendata/**

Note that you can use globs, as defined by the glob package.

Here is an example file that enables two lint rules:

linter:
  rules:
    - camel_case_types
    - empty_constructor_bodies

Check out all the available Dart lint rules.

You can combine the analyzer section and the linter section into a single configuration. Here is an example:

analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
linter:
  rules:
    - camel_case_types

For more information, see the docs for customizing static analysis.

Background

The APIs in this package were originally machine generated by a translator and were based on an earlier Java implementation. Several of the API's still look like their Java predecessors rather than clean Dart APIs.

In addition, there is currently no clean distinction between public and internal APIs. We plan to address this issue but doing so will, unfortunately, require a large number of breaking changes. We will try to minimize the pain this causes for our clients, but some pain is inevitable.
