前言
Flutter是谷歌的移動(dòng)UI框架，可以快速在iOS和Android上構(gòu)建高質(zhì)量的原生用戶界面。 Flutter可以與現(xiàn)有的代碼一起工作。在全世界，F(xiàn)lutter正在被越來越多的開發(fā)者和組織使用，并且Flutter是完全免費(fèi)、開源的。
-
快速開發(fā)
- 毫秒級(jí)的熱重載，修改后，您的應(yīng)用界面會(huì)立即更新。使用豐富的、完全可定制的widget在幾分鐘內(nèi)構(gòu)建原生界面。
-
富有表現(xiàn)力和靈活的UI
- 快速發(fā)布聚焦于原生體驗(yàn)的功能。分層的架構(gòu)允許您完全自定義，從而實(shí)現(xiàn)難以置信的快速渲染和富有表現(xiàn)力、靈活的設(shè)計(jì)。
-
原生性能
- Flutter包含了許多核心的widget，如滾動(dòng)、導(dǎo)航、圖標(biāo)和字體等，這些都可以在iOS和Android上達(dá)到原生應(yīng)用一樣的性能。
官方說的這么牛x，能不了解一下嗎！本系列為本人學(xué)習(xí)flutter的學(xué)習(xí)筆記，重在記錄學(xué)習(xí)中遇到的問題。
環(huán)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)
安裝與環(huán)境搭建
參考flutter中文網(wǎng)或者自行Google，前人之述備矣，此處不再贅述。
配置編輯器
本人為iOS開發(fā)，未安裝過Android Studio，所以不具備安卓開發(fā)環(huán)境。
為了親自體驗(yàn)一下不同編輯器，所以安裝了IntelliJ IDEA 和 VS Code體驗(yàn)flutter開發(fā)。VS Code的配置參考官方教程。IntelliJ IDEA的配置參考官方教程。IntelliJ IDEA需要安裝flutter和dart插件，在IntelliJ IDEA安裝插件需要翻墻，也可以去官方插件庫搜索插件從磁盤安裝。從磁盤安裝插件極有可能重啟應(yīng)用后報(bào)錯(cuò)閃退，修復(fù)方法是在應(yīng)用目錄下~/Library/Application Support/<PRODUCT><VERSION>中把安裝的插件刪除即可。推薦翻墻從應(yīng)用內(nèi)搜索插件安裝插件。
常用命令

終端
終端在適合的目錄下運(yùn)行flutter create flutter_app創(chuàng)建一個(gè)名為flutter_app的應(yīng)用。
IntelliJ IDEA
從Flutter入門應(yīng)用程序模板創(chuàng)建一個(gè)新的Flutter IntelliJ項(xiàng)目：
- 在IntelliJ中，在 ‘Welcome’ 窗口點(diǎn)擊 Create New Project
- 或者在主界面 File>New>Project…
- 在菜單中選擇 Flutter , 然后點(diǎn)擊 Next.
- 輸入Project name 和 Project location，點(diǎn)擊 Finish.
VS Code
從Flutter入門應(yīng)用程序模板創(chuàng)建一個(gè)新的Flutter項(xiàng)目:
- 打開 Command Palette (Ctrl+Shift+P (Cmd+Shift+P on macOS)).
- 選擇 Flutter: New Project命令并回車。
- 輸入Project name 和 Project location
開發(fā)工具簡(jiǎn)單應(yīng)用教程
英文還可以的同學(xué)參考官方的英文教程，官方提供了Android Studio / IntelliJ和VS Code的簡(jiǎn)單開發(fā)教學(xué)。
IntelliJ中直接在頂部工具欄就可以操做，VS Code按F5運(yùn)行項(xiàng)目并顯示工具欄。
