therecipe / flutter Goto Github PK

BINARIES

This repo showcases the PoC of the new interop module of therecipe/qt, as well as the new flutter module containing a custom flutter desktop embedder, it is also a part of a series of language bindings for Qt.

The series consists of the Go, the JavaScript/TypeScript, the Dart/Flutter, the Haxe and the Swift binding for Qt.

Other bindings to languages such as Kotlin, Java, C#, Python, Node.js and Ruby are planned as well.

Almost all Qt functions and classes are accessible from Dart and you should be able to find everything you need to build fully featured Qt applications in Dart, the feature-set shown represents only a small portion of all the features available.

However this is still very much experimental, and there are known memory leaks and other limitations such as the missing support for enums.

Another caveat is that the flutter embedder currently only supports debug builds and the interop api also isn't working on windows yet.

It's planned to make the custom flutter embedder optional, and support plain Dart projects in the future as well.

Also, a word of warning, the interop api isn't frozen yet and might change in the future.

If you want to dig around, checkout the main.dart and the internal.dart files were all of the logic used for this binding is buried.

Setup therecipe/qt and install Flutter: https://flutter.dev/docs/get-started/install

After adding the flutter/bin dir to your PATH, you can use qtdeploy to build and deploy the showcase.

If you want to rebuild the flutter code during development, you can use flutter build bundle.

Then use go run -tags=minimal . to build the go code and run the showcase. (Maybe take a look into the make.sh script as well.)

To enabled hot reloading, use something like: flutter attach --debug-uri=http://127.0.0.1:60123/xyzxyzxyz/

Also, the linux, linux_static, darwin and darwin_static docker images should contain the flutter sdk now as well.

Docker windows builds should work also, but only if you run them after building with at least one of the four images listed above.

If you want to re-generate the Dart binding, you can use the gen.sh script to do so.
