want to learn Flutter get started quickly, and there are also some example applications written by me for reference. 4 | 5 | ## Flutter_Demo Introduction 6 | 7 | ### Four major aspects 8 | Introduced from the following four aspects: 9 | 1. Common basic components 10 | 2. Commonly used functional components include mainstream state management frameworks 11 | 3. Some example demos written 12 | 4. Tool-type function arrangement 13 | 14 | - This project is relatively casual and only suitable for entry-level reference, and it will be maintained slowly when there is time in the future. 15 | 16 | Most of the examples in the project are detailed on my nuggets: 17 | [My Nuggets Homepage](https://juejin.cn/user/2620848963859582) -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 2 | # Flutter_Demo 个人Flutter 入门学习的记录 3 | 4 | > 该项目可以快速让想学习Flutter的同学快速了解入手，同时里面还有我自己写的一些例子应用也可参考。 5 | 6 | ## Flutter_Demo 介绍 7 | 8 | ### 四大方面 9 | 从以下这四个方面介绍： 10 | 1、常用基础组件 11 | 2、常用功能性组件 包含主流状态管理框架 12 | 3、写的一些例子demo 13 | 4、工具型功能整理 14 | 15 | - 该项目比较随意，只适合入门参考，后续有时间也会慢慢维护。 16 | 17 | 项目中的示例大部分都在我的掘金上有详细的介绍： 18 | [我的掘金主页](https://juejin.cn/user/2620848963859582) 19 | 20 | -------------------------------------------------------------------------------- /analysis_options.yaml: -------------------------------------------------------------------------------- 1 | # This file configures the analyzer, which statically analyzes Dart code to 2 | # check for errors, warnings, and lints. 3 | # 4 | # The issues identified by the analyzer are surfaced in the UI of Dart-enabled 5 | # IDEs (https://dart.dev/tools#ides-and-editors).
