Support a light/dark mode toggle (from the command line and IDEs) #59495
Description
A frequent request from the last Flutter developer survey was for an easier method of testing light/dark mode changes. Currently, a user needs to manually change the theme settings or adjust phone settings to see the difference. Instead we should add a toggle from the CLI, and eventually devtools/Intellij/Vscode that allows developers to override the current setting.
This can be implemented in several parts:
- Add a framework service extension which overrides the Binding value of Brightness, similar to how the platform toggle does it.
- Add a CLI option to toggle the brightness (b?) and wire it up.
- For each IDE, expose functionality (as appropriate) to toggle the brightness. This would be left up to the owners of devtools, Intellij, and VSCode
