Towards https://github.com/flutter/flutter/issues/160617 Noticed the `opacity` and `withOpacity` deprecations were supported by dart fix, but not the others. Adding them here. But strange too given `dart:ui` does not support dart fix (https://github.com/dart-lang/sdk/issues/59764).. --- We think since `painting.dart` exports `dart:ui`, this is somewhat of a workaround. If a user has this atop their file: ```dart import 'package:flutter/painting.dart'; // 👍 dart fix will work here ``` If instead ```dart import 'dart:ui'; // ❌ dart fix will not work here ``` Will continue to follow up on dart fix support for `dart:X` libraries, for now hopefully this will help! ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
