Adds initial support for flutter create of apps and plugins. This is derived from the current FDE example app and sample plugin, adding template values where relevant.
Since the APIs/tooling/template aren't stable yet, the app template includes a version marker, which will be updated each time there's a breaking change. The build now checks that the template version matches the version known by that version of the tool, and gives a specific error message when there's a mismatch, which improves over the current breaking change experience of hitting whatever build failure the breaking change causes and having to figure out that the problem is that the runner is out of date. It also adds a warning to the create output about the fact that it won't be stable.
Plugins don't currently have a version marker since in practice this is not a significant problem for plugins yet the way it is for runners; we can add it later if that changes.
Fixes#30704
When generating the plugin registrant for Linux, also generate a
makefile that can be included in the app-level Makefile to manage all of
the plugin targets and flags, exporting them in a few known variables
for use in the outer makefile.
Part of #32720
Generates a Property Sheet for Windows builds containing link and include path
information for any included plugins. This allows automating part of the process
of integrating plugins into the build that is currently manual.
To support this change, refactored msbuild_utils into a PropertySheet class so that
it can be used to make different property sheets.
This makes ephemeral symlinks to each plugin, for use by build systems.
This is similar to the logic implemented in the Podfile on iOS and
macOS, but managed internally to the Flutter tool.
Exploration for addressing #32719 and #32720
Related to #41146
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
* Generate projects using the new Android embedding
* Add comment about usesNewEmbedding:true
* Feedback
* Rework way to detect new embedding in new apps
Adds very preliminary support for Windows and Linux plugins:
- Adds those platforms to the new plugin schema, initially supporting just a plugin class.
- Adds C++ plugin registrant generation for any Windows or Linux plugins found.
This doesn't have yet have any build tooling for either platform, so anyone using the generated registrant still needs to do manual build configuration. This reduces the manual work, however, and creates a starting point for future tooling work.
As with all Windows and Linux work at this time, this is not final, and subject to change without warning in the future (e.g., Windows could potentially switch to a C# interface, or
'linux' may change to 'gtk' or 'linux_gtk' in pubspec.yaml).
