In this example, List will get different props.children value. And here are my codes:

const { AutoLayout, Text } = figma.widget;



function List(props: any) {

  console.log('List children length', props.children.length, props.children);

  return <AutoLayout name={props.name}>{props.children}</AutoLayout>;

}



export function MenuUsage() {

  return (

    <AutoLayout>

      <List>

        {[1, 2].map((number) => (

          <Text key={number}>{`${number}`}</Text>

        ))}

      </List>

      <List

        children={[3, 4].map((number) => (

          <Text key={number}>{`${number}`}</Text>

        ))}

      ></List>

    </AutoLayout>

  );

}
