I received this error when I tried to run my flutter app on an emulator in android-studio. How do I solve this issue?


Solution 1: Vishesh Pandey

Platform.packageRoot member variable now has been removed in the platform plugin. All you need to do is override dependency to the previous version.

dependency_overrides:
  platform: 2.2.0


Solution 2: Maisam Hindawi

It worked but by using

dependencies:

platform: ^3.1.0
