## What it is
The source manuscript for 'Flutter in Action, 2nd Edition', a free online Chinese-language book teaching Flutter mobile development from basics to advanced framework internals. It covers widgets, layout, scrolling, animation, networking, internationalization, and rendering principles, with a full example app.

- you need explanations of Flutter framework internals like Element and RenderObject
- you prefer learning via progressive chapters with runnable examples

## When to avoid
- you need English-language documentation
- you want an up-to-date reference for the latest Flutter APIs, as some chapters are unfinished
- you need a quick API reference rather than a tutorial

## Facets

- maturity: active
- function: documentation, developer-tools
- domain: mobile-development, tutorials, cross-platform
