_MapboxMapState.onPlatformViewCreated The method 'call' was called on null.

[MATTYGILO]

I am using Flutter Mapbox version:
mapbox_gl: ^0.9.0

I came across this error:

[VERBOSE-2:shell.cc(210)] Dart Unhandled Exception: NoSuchMethodError: The method 'call' was called on null.

I solved this by setting onStyleLoadedCallback to and empty method:

This error because you use the minSdkVersion in android under the 20.
set minSdkVersion 20 in build.gradle file.
