Building

Steps on linux (WSL) system:

git clone https://github.com/flutter/gallery.git flutter_gallery
cd flutter_gallery
git checkout d77920b4ced4a105ad35659fbe3958800d418fb9
flutter pub get
flutterpi_tool build --release --cpu=pi4
scp -r ./build/flutter_assets pi@raspberrypi:/home/pi/flutter_gallery

Get warning:

2023/11/29 14:04:38.899981 system_key.go:129: cannot determine nfs usage in generateSystemKey: cannot parse mountinfo: incorrect number of tail fields, expected 3 but found 4

Running

Steps on pi:

flutter-pi --release ~/flutter_gallery

Get error:

flutter-pi.c: Error: Could not load engine from any location. Make sure you have installed the engine binaries.

The libflutter_engine.so is included inside the flutter_gallery directory

If the engine can't be loaded, could also be it's for the wrong architecture, or otherwise not executable (somehow).

Configuring and building flutter-pi with -DCMAKE_BUILD_TYPE=Debug should give more information. What does file ~/flutter_gallery say for you?
