Answer 1

It worked for me by changing the image_picker version to image_picker: ^0.6.0+9

Answer 2

As the last error says:

The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app. See for more information on the problem and how to fix it.

You need to migrate your Android module to AndroidX. Most of the flutter dependencies now built with AndroidX, so you better to upgrade your project too.

In Android Studio or IntelliJ, you can migrate by accessing menu Refactor -> Migrate to AndroidX...
