  Running Gradle task 'assembleRelease'... Done                     303.8s (!)
  The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
  Building plugin firebase_messaging...
  The plugin firebase_messaging could not be built due to the issue above.
