Build me a Flutter helper app for developers that shows a big collection of common Flutter components, with live demo pages for each one and short Chinese explanations for how they work and when to use them.

I want it to feel like a clean reference app people can open when they are learning Flutter or need to quickly check a widget. Include a home screen that organizes the demos clearly, a search or browsing view so it is easy to find things, and detail pages for each component with examples and notes. Make the app easy to navigate on both iOS and Android, and keep the design simple and practical. If you need to, look up the current Flutter docs online and follow best practices for the widgets and layout.
