Could not open file for bundled shader "UnlitVertex".
this appears when compilation is done inside src/flutter, and not src (buildroot), which otherwise works. this was my fix so far (Not A Contribution):
- cd src/flutter
- python3 ./tools/gn \
+ cd src
+ python3 ./flutter/tools/gn \
--out-dir "$PWD" \
--no-goma \
--clang \
--no-backtrace \
--no-stripped \
--prebuilt-dart-sdk \
--unoptimized \
--gn-args 'ccache_bin="sccache" use_ccache=true' \
--runtime-mode=debug
