Running Flutter with local Dart SDK

gistfile1.md

1. Setup Flutter engine & et
2. Create Local Dart SDK

You may need to do:

• ulimit -n 200000
• Add gcloud to PATH (flutter/engine/src/flutter/buildtools/mac-arm64/gcloud/bin)
  • gcloud auth application-default login

Make any changes to any files needed

Then run ./tools/build.py --mode release --arch arm64 create_sdk

3. Setup engine and flutter cache to use local dart SDK

I just delete the actual artifacts and symlink to the local one. Will need to delete caches after done testing so artifacts are re-downloaded.

rm -rf $FLUTTER_ROOT/bin/cache/dart-sdk
cd $FLUTTER_ROOT/bin/cache
ln -sf  /path/to/local/dart-sdk/sdk/xcodebuild/ReleaseARM64/dart-sdk
rm -rf $FLUTTER_ROOT/engine/src/flutter/prebuilts/macos-arm64/dart
rm -rf $FLUTTER_ROOT/engine/src/flutter/prebuilts/macos-arm64/dart-sdk
cd $FLUTTER_ROOT/engine/src/flutter/prebuilts/macos-arm64
ln -sf  /path/to/local/dart-sdk/sdk/xcodebuild/ReleaseARM64/dart-sdk

4. Run flutter app with local tools & engine

Clear tools snapshot and run arbitrary flutter command to rebuild

rm $FLUTTER_ROOT/bin/cache/flutter_tools.snapshot && flutter help

Then in a flutter project et run --config ios_debug
