i think i got the answer... please correct me if i am wrong. what i did to solve the problem is... i wrote these commands to terminal... 1. flutter clean 2. flutter pub cache repair then i rebuild the app and it works. also i saw a lot of time the app seemed behaving not as expected. so in that case i just simply closed the app from device and again rebuild it and it works... i don't know why yet it happens. what i am guessing is it's a bug. may be google needs to fix these or give us a clear documentation about this fact.

I found a way to resolve. Well mostly trial and error sort of thing.

  1. In Android Studio, Go to file => settings => System Settings => Android SDk to confirm you have the SDK installed for the android version you're running. To confirm the android version you have click on AVD manager, it should be shown on Target.
  2. Check that you have internet connection in your emulator, a cold reboot should help fix that, if not Wipe Data.
  3. Check that you can open Google map on your android emulator.
  4. Go to emulator settings which that 3 horizontal dots or ellipses and go to settings, OpenGL ES API Level to Auto Select.
  5. Also make sure minSdkVersion 20 in android/app/build.gradle

Hope this helps anyone struggling at the moment.
