render method

@override void render(Buffer buffer, Rect area)

Renders the widget onto the provided buffer within the specified area.

Implementation

@override
void render(Buffer buffer, Rect area) {
  final clampedWidth = area.width.clamp(
    constraints.minWidth,
    constraints.maxWidth,
  );
  final clampedHeight = area.height.clamp(
    constraints.minHeight,
    constraints.maxHeight,
  );

  if (clampedWidth <= 0 || clampedHeight <= 0) return;

  final childArea = Rect(area.x, area.y, clampedWidth, clampedHeight);
  final viewport = Viewport(buffer, childArea);
  child.render(viewport, Rect(0, 0, clampedWidth, clampedHeight));
}
