前言

Flutter是谷歌的移动UI框架，可以快速在iOS和Android上构建高质量的原生用户界面。 Flutter可以与现有的代码一起工作。在全世界，Flutter正在被越来越多的开发者和组织使用，并且Flutter是完全免费、开源的。

快速开发
- 毫秒级的热重载，修改后，您的应用界面会立即更新。使用丰富的、完全可定制的widget在几分钟内构建原生界面。
富有表现力和灵活的UI
- 快速发布聚焦于原生体验的功能。分层的架构允许您完全自定义，从而实现难以置信的快速渲染和富有表现力、灵活的设计。
原生性能
- Flutter包含了许多核心的widget，如滚动、导航、图标和字体等，这些都可以在iOS和Android上达到原生应用一样的性能。

官方说的这么牛x，能不了解一下吗！本系列为本人学习flutter的学习笔记，重在记录学习中遇到的问题。

环境配置

Flutter 1.0.0
Dart 2.1.0 (build 2.1.0-dev.9.4 f9ebf21297)
Xcode Version 10.1 (10B61)
IntelliJ IDEA 2018.3.2 (Ultimate Edition)
VS Code 1.30.1 (1.30.1)

安装与环境搭建

参考flutter中文网或者自行Google，前人之述备矣，此处不再赘述。

配置编辑器

本人为iOS开发，未安装过Android Studio，所以不具备安卓开发环境。
为了亲自体验一下不同编辑器，所以安装了IntelliJ IDEA 和 VS Code体验flutter开发。VS Code的配置参考官方教程。IntelliJ IDEA的配置参考官方教程。IntelliJ IDEA需要安装flutter和dart插件，在IntelliJ IDEA安装插件需要翻墙，也可以去官方插件库搜索插件从磁盘安装。从磁盘安装插件极有可能重启应用后报错闪退，修复方法是在应用目录下~/Library/Application Support/<PRODUCT><VERSION>中把安装的插件删除即可。推荐翻墙从应用内搜索插件安装插件。
