Passing invalid shader asset to ui.FragmentProgram.fromAsset crashes application #108037
Description
Testing on my branch where I have not yet configured the shader compiler to conditionally emit SKSL, I receieved the following error on linux desktop:
[ERROR:flutter/impeller/base/validation.cc(27)] Impeller Runtime stage has invalid magic. Perhaps the stage information is for the incorrect backend or the data is corrupted?
[ERROR:flutter/impeller/base/validation.cc(38)] Break on ImpellerValidationBreak to inspect point of failure.
Lost connection to device.
We should make sure that we can throw a Dart exception or similar.
