ConditionalParentBuilder constructor

const ConditionalParentBuilder({
  1. Key? key,
  2. required ParentBuilder builder,
  3. required Widget child,
})

A widget that allows developers to conditionally wrap the child widget with a parent widget.

In the following real-world example, we conditionally wrap the child widget tree with a context menu if the message is not deleted:

ConditionalParentBuilder(
  builder: (context, child) {
    if (!widget.message.isDeleted) {
      return ContextMenuArea(
        builder: (context) => buildContextMenu(),
        child: child,
      );
    } else {
      return child;
    }
  },
  child: Material(...),
),

This example can be found in the stream_chat_flutter source code under src/message_widget/message_widget.dart.

Implementation

const ConditionalParentBuilder({
  super.key,
  required this.builder,
  required this.child,
});
