Question

I'm getting this errors while building my app on my phone:

Answer 1

As it is mentioned in the Flutter docs, that one should avoid installing Flutter in a directory like C: as it requires elevated administrator privileges sometimes. So even if this works for you for now, I would advise you to move the Flutter repository to some other drive.

Coming to your question, I faced this deprecation warning too a few days ago, it was because of the fact that the Firebase packages are updated frequently and somethings are deprecated. Please use the latest version of Firebase Core, it resolved the problem for me.

Answer 2

Welcome to SOF.

Seems WebView has problems and caused apps like GMail and Flutter built apps to crash, Google fixed it, please update these two:
