Thanks in advance for helping me.


Solution

  • Flutter projects created on the master channel will generate an android/settings.gradle file that points to a file in the Flutter tool that's present in 1.18.0-dev.5.0 (currently available on all channels).

    Switching from master -> stable "downgrades" Flutter relative to that change, and the file is no longer present.

    You can work around this by regenerating your android/settings.gradle while on stable:

    $ rm android/settings.gradle
    $ flutter create .
    

    See the GitHub issue for more details.
