build method

@override Widget build()

Subclasses should override this function to actually call the appropriate build function (e.g., StatelessWidget.build or State.build) for their widget.

Implementation

@override
Widget build() {
  // 使用 Builder 确保获取到正确的 BuildContext
  return consumer.buildProviderTree(
    Builder(
      builder: (context) {
        consumer.updateContext(context);
        return super.build();
      },
    ),
  );
}
