A Dart runner for Flutter Windows apps — no C++ compiler required.

package:win32_runner is an experimental package that replaces the default C++ runner generated by flutter create with a pure Dart alternative, letting you build and run Flutter Windows apps without a C++ toolchain installed.

⚠️ Experimental: This package is a proof-of-concept and is not suitable for production use. Plugin support is not yet implemented.

🚀 Getting Started

The example subdirectory contains a ready-to-use sample. Follow the steps below to run an existing Flutter app on Windows using the Dart runner.

1. Clone the repository

C:\src> git clone https://github.com/halildurmus/win32.git
C:\src> cd packages/win32_runner

2. Install dependencies

C:\src\win32\packages\win32_runner> dart pub get

3. Create a sample Flutter app

C:\src\win32\packages\win32_runner> cd example
C:\src\win32\packages\win32_runner\example> flutter create simpleapp
C:\src\win32\packages\win32_runner\example> cd simpleapp

4. Compile the Dart runner

C:\src\win32\packages\win32_runner\example\simpleapp> dart build cli -t ..\win32_runner.dart -o build

5. Compile Flutter code and assets

C:\src\win32\packages\win32_runner\example\simpleapp> flutter assemble -dTargetPlatform=windows-x64 --output=build -dBuildMode=release release_bundle_windows-x64_assets

6. Run your Flutter app

C:\src\win32\packages\win32_runner\example\simpleapp> .\build\bundle\bin\win32_runner.exe

You should now see your Flutter app running via the Dart runner:
