The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve
the incompatibility.

Answer 1

As you can read in error message, the plugin you used has some AndroidX incompabilities. Try to execute flutter packages get and flutter clean, maybe something cached. Then try build again.
