Engine run configuration was invalid

Question

The flutter APP stays on the startup page.

IOS online installation stays on the startup page.

Error:

14:00:06 Hui-teki-iPhone Runner →  <Warning>: Failed to find snapshot: /var/containers/Bundle/Application/2F947DB6-005F-4E6D-ACEB-96E82F201FCC/Runner.app/flutter_assets/kernel_blob.bin

A flutter application, the computer installation is fine, the online installation stays on the startup page.

Answer 1

I had same problem when I was back to stable channel that used an old engine respect to master channel.

Try to use master channel:

flutter channel master
flutter upgrade
