Flutter Processing

A Flutter port of Processing.

This project is not affiliated with the Processing project, or related organizations.

The goal of flutter_processing is to provide the same easy learning environment as Processing, but with the additional utility of a production-ready UI toolkit, called Flutter. With traditional Processing, there is minimal professional value in the underlying language. With flutter_processing, the underlying tool, Flutter, is sufficient for employment as an app UI developer. flutter_processing offers an educational tool and an employment opportunity all in one.

Getting Started

To play with some demos, clone this repository and run the example app!

To paint a canvas with a sketch in Flutter, the way you would in Processing, display a Processing widget and implement a Sketch.

void main() {
  runApp(
    MaterialApp(
      home: Processing(
        sketch: Sketch.simple(
          setup: (sketch) async {
            // TODO: do your typical Sketch setup
            //       stuff here. Call methods on
            //       the provided sketch object.
          },
          draw: (sketch) async {
            // TODO: do your typical Sketch drawing
            //       stuff here. Call methods on
            //       the provided sketch object.
          },
        ),
      ),
    ),
  );
}

To retain and access variables in your Sketch, or to implement a Sketch in a more traditional way, subclass Sketch:

void main() {
  runApp(
    MaterialApp(
      home: Processing(
        sketch: MySketch(),
      ),
    ),
  );
}

class MySketch extends Sketch {
  @override
  Future<void> setup() async {
    // TODO: do setup stuff here
  }

  @override
  Future<void> draw() async {
    // TODO: do drawing stuff here
  }
}
