`package:native_assets_builder` and `package:native_assets_cli/native_assets_cli_internal.dart` are used in [`package:dartdev`] and [`package:flutter_tools`].

Dartdev and Flutter Tools are the commandline interfaces for `dart ...` and `flutter ...` commands.

## Downstream builds

Both Dartdev and Flutter Tools are built in open source, and inside g3.

* Dartdev as part of the Dart SDK build on the [Dart CI].
* Dartdev as part of the g3 build (see CBuild comments on CLs on [Gerrit]).
* Flutter Tools as part of the workflows on GitHub.

The versions used in these different places are as follows:

* The Dart SDK uses pinned dependencies in [DEPS], the current hash is in `native_rev`.
* The Flutter build on GitHub ussed published dependencies in [its `pubspec.yaml`].

## Rolling

The above means the following.

Breaking changes to `native_assets_cli`, `native_assets_builder`, and
`native_toolchain_c` have to be rolled into the Dart SDK with a CL that
runs all the `pkg` bots:
```
Cq-Include-Trybots: luci.dart.try:pkg-win-release-try,pkg-win-release-arm64-try,pkg-mac-release-try,pkg-mac-release-arm64-try,pkg-linux-release-try,pkg-linux-release-arm64-try,pkg-linux-debug-try
```
The CI on this repo runs with path dependencies between these packages
which corresponds to the path dependencies used in the DEPS file in the Dart
SDK.

Breaking changes to `native_assets_cli` and `native_assets_builder`
have to be rolled into the packages/flutter_tools in the flutter/flutter repo.
This package uses published dependencies.
So this requires:

1. Land a commit that sets the `native_assets_cli` to a stable version.
2. Publish `native_assets_cli` on pub.dev.
3. Land a commit that sets `native_assets_builder` to a stable version,
   depends on the published version of `native_assets_cli`, and
   removes the `publish_to: none`.
4. Publish `native_assets_builder` on pub.dev.
5. (Repeat these steps for `native_toolchain_c`.)
6. Finally, land a commit that sets all versions to WIP, and adds
   `publish_to: none` back in.
