Automatically wire dependencies for native plugins (#8891)
Go through all packages brought in by pub, and write the name and path of every one that is a flutter plugin into .flutter-plugins.
In android/settings.gradle and ios/Podfile, read in .flutter-plugins, if that file exists. The Android / iOS code from the plugins is automatically added as dependencies of the native code of the app.
