matrix_gesture_detector

Description:

matrix gesture detector

matrix_gesture_detector #
MatrixGestureDetector detects translation, scale and rotation gestures
and combines them into Matrix4 object that can be used by Transform widget
or by low level CustomPainter code. You can customize types of reported
gestures by passing shouldTranslate, shouldScale and shouldRotate
parameters.
Getting Started #
The usage is as follows:
MatrixGestureDetector(
onMatrixUpdate: (Matrix4 m, Matrix4 tm, Matrix4 sm, Matrix4 rm) {
setState(() {
matrix = m;
});
},
child: SomeWidgetThatUsesMatrix(
matrix: matrix,
...
)
)
copied to clipboard
here: SomeWidgetThatUsesMatrix could be a Transform widget
(transform_demo.dart) or a CustomPaint widget which
CustomPainter uses Matrix4 in its low level drawing code
(custom_painter_demo.dart).
