Changes the analyzer and related packages so that when they refer to diagnostic constants, they do so via the import prefix `diag`, which refers to the appropriate `diagnostic.dart` file containing the top level diagnostic constant declarations, rather than the static declarations inside `DiagnosticCode`-derived classes (which will soon be removed). This CL was created by the following steps: - Run the script `pkg/analyzer_utilities/tool/messages/switch_to_toplevel_diagnostics.dart`. - Execute `dart fix --apply --code=unused_import,unnecessary_import` on the following directories (this removes imports that are no longer necessary due to the change): - `pkg/analysis_server` - `pkg/analyzer` - `pkg/linter` - `pkg/analysis_server_plugin` - `pkg/analyzer_plugin` - `pkg/analyzer_testing` - `pkg/front_end` - `pkg/analyzer_cli` - Execute `dart format` on the following files and directories: - `pkg/analysis_server` - `pkg/analyzer` - `pkg/linter` - `pkg/analysis_server_plugin` - `pkg/analyzer_plugin` - `pkg/analyzer_testing` - `pkg/front_end/test/scanner_test.dart` (Note that `pkg/front_end` and `pkg/analyzer_cli` are not re-formatted as whole directories because they contain `.dart` files that are test cases rather than source code, and reformatting those files might change test expectations.) - Manually add `diag` to pkg/front_end/test/spell_checking_list_tests.txt. - Manually fix the ignore comment in `pkg/analyzer_testing/lib/src/analysis_rule/pub_package_resolution.dart`. (The script `switch_to_toplevel_diagnostics.dart` automatically adds it after `import 'package:analyzer/src/diagnostic/diagnostic.dart' as diag;`, but then executing `dart format` bumps the ignore comment to the following line, where it has no effect.)

SDK development code analysis
dartanalyzer used to be the tool for statically analyzing dart code
at the command line. However, this tool has been replaced with
dart analyze for this purpose in current SDKs and will no longer
be published on pub.
Do not depend on the command line interface or other semantics in
this directory as it is now an internal tool for SDK development, used
as the dart2analyzer "compiler" for tools/test.py in the SDK.
It is configured as part of the test runner,
here.
SDK development usage
For SDK development, run analysis from the test tool to validate analysis conclusions on language samples in the testing directory. From the root of the SDK:
tools/test.py --build --use-sdk -c dart2analyzer co19 language
This will build the Dart VM and compile dartanalyzer into a snapshot, then use
that snapshot while analyzing those directories under testing/. Without
--use-sdk, test.py will use the source code version of the analyzer
instead of the compiled one, which can be useful for debugging.
