layout method

  1. @override
void layout(
  1. Context context,
  2. BoxConstraints constraints, {
  3. bool parentUsesSize = false,
})
override

First widget pass to calculate the children layout and bounding box

Implementation

@override
void layout(Context context, BoxConstraints constraints,
    {bool parentUsesSize = false}) {
  super.layout(context, constraints, parentUsesSize: parentUsesSize);

  final datasets = Chart.of(context).datasets;
  final size = constraints.biggest;

  gridBox = PdfRect(0, 0, size.x, size.y);

  for (final dataset in datasets) {
    dataset.layout(context, BoxConstraints.tight(gridBox.size));
  }
}
