pubspec.yaml files.
There were `pubspec.yaml` files in `tools/` that were not included in the global package config. That means that their imports were irrelevant, which could be misleading. And if any tool would look at the `pubspec.yaml` file, it might be inconsistent with the actual package resolution. Makes every `pubspec.yaml` file either be included by the `tools/generate_package_config.dart` script, or deletes them if they seem to be stale and unused. (Compare vs. `git ls-files '**/pubspec.yaml'`.) Excepted `tools/dart2js/sourceMapViewer/pubspec.yaml`. The entire directory might be stale. The dependencies of that pubspec are not SDK dependencies otherwise, the pubspec has no SDK min-version, which is now a requirement, and the README refers to a *packages directory*. Keeping as-is and filing issue to have owners take a look. Added `lib/` directory to `tools/` to avoid `tools/bots/` being inside the package URI root of the `tools/` package, which would cause its `../../pkg/...` import to fail. Makes every `pubspec.yaml` file use a `^...` SDK constraint instead of the longer `>= ... < ...` format. Tested: No new tests, goal is to keep running the same way Change-Id: I688e463fe985fc4de43550a1f4c7ff350536cffc Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/414020 Commit-Queue: Lasse Nielsen <lrn@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Sigurd Meldgaard <sigurdm@google.com> Reviewed-by: Brian Quinlan <bquinlan@google.com>
Dart
An approachable, portable, and productive language for high-quality apps on any platform
Dart is:
-
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
-
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
