自定义组件的meta.ts文件中isRequired字段的作用

请问在自定义组件的时候，执行npm run lowcode:dev命令生成的lowcode文件夹中的meta.ts文件中isRequired字段的作用是什么呢，感觉设置为true或者false都没有什么不同

Start with the generated lowcode/meta.ts produced by npm run lowcode:dev and compare custom-component metadata with isRequired set to true and false. Clarify the field's effect and document the observed behavior; the issue is complete when the distinction, or lack of one, is explained.
