android - Flutter 1.9: D/skia ( 5106): Shader compilation error

Question

I've created a simple Flutter 1.9.1+hotfix.4 application using Android Studio 3.5.1. After adding successfully a new virtual device (Nexus 6) and tried to run my app, I got this error:

Answer 1

I solved my Shader compilation error by changing emulator's settings.

Press that ... button which is located on the side panel of emulator, and go to Settings section. There, go to Advanced tab and change OpenGL ES API level to Compatibility (OpenGL ES 1.1/2.0).

Do not forget to close and rerun the emulator after this change. On the first run, emulator could pop a warning on its screen and it would take a while to get ready, but do not worry.
