controller property Null safety
The controller for this render object.
Implementation
PlatformViewController get controller => _controller;
covariant
This value must not be null, and setting it to a new value will result in a repaint.
Implementation
set controller(covariant PlatformViewController controller) {
assert(controller != null);
assert(controller.viewId != null && controller.viewId > -1);
if (_controller == controller) {
return;
}
final bool needsSemanticsUpdate = _controller.viewId != controller.viewId;
_controller = controller;
markNeedsPaint();
if (needsSemanticsUpdate) {
markNeedsSemanticsUpdate();
}
}
