Library for displaying CGM files in Flutter
Flutter implementation of the cgm library.
Note: This library is still in development and does not yet support all CGM features. Bugs and missing features are likely to be present.
Features #
- Drawing the commands of a parsed CGM file to a Canvas, or displaying them in a widget.
Usage #
To paint the commands to a canvas:
final cgm = CGM.fromFile(file);
// Create a canvas to draw the CGM commands on
// The paramter canvas is an instance of Flutter's Canvas class
final cgmCanvas = FlutterCGMCanvas(canvas);
final display = CGMDisplay(cgm);
// Paint the CGM commands to the canvas
display.paint(cgmCanvas);
To display the CGM file in a stateful widget:
class ExampleWidget extends StatefulWidget {
@override
_ExampleWidgetState createState() => _ExampleWidgetState();
}
class _ExampleWidgetState extends State<ExampleWidget> {
late final CGM cgm;
@override
void initState() {
super.initState();
final file = File('path/to/file.cgm');
cgm = CGM.fromFile(file);
}
@override
Widget build(BuildContext context) {
return CGMWidget(
cgm: cgm,
);
}
}
