文章首次整理發(fā)布自個人博客：一之筆:如何用Pod集成Flutter

image

要求：

1. Macos 已經(jīng)配置好flutter開發(fā)環(huán)境；
2. 支持Cocopods

可用如下命令查看Flutter是否配置成功

flutter doctor -v

如果終端打印如下，基本就OK了,Android的環(huán)境不用管，iOS可以就行；

問題

很久之前，也不能說很久，大概2個月前吧，公司決定未來要遷移到跨平臺開發(fā)中，需要拿APP部分功能做一個嘗試，看實際效果，然后我就看了下Flutter，按照Flutter中文網(wǎng)配置了開發(fā)環(huán)境，并且編譯了一個 Hello Word 示例程序，成功運行；

項目組專門有一個同學(xué)負(fù)責(zé)寫Flutter功能模塊，我只需要集成并且跟Flutter數(shù)據(jù)交互，完成業(yè)務(wù)即可；

問題就出在這兒，我把Flutter模塊更換成公司私有倉庫時，更新代碼，執(zhí)行編譯打包，發(fā)現(xiàn)Xcode編譯通過，但是，F(xiàn)lutter無法渲染界面；我就很崩潰；重新查了下資料，發(fā)現(xiàn)網(wǎng)上用Pod集成Flutte的資料很少，很多的是，手動集成；

手動集成

手動集成，真是太不方便了，可以看看這個文章:iOS老項目集成Flutter（iOS混編Flutter),t太繁瑣了，各種配置，如果你喜歡手動的話，就看那個文章就可以；

現(xiàn)在項目基本都是模塊化，F(xiàn)lutter基本也是以Framework的形式引入在項目中，如果Flutter模塊更新后，我們只需要執(zhí)行 pod 更新一下，就可以了，真是太方便了；

Pod集成

• 在 Podfile 中，引入 Flutter 模塊，具體就是下面兩行代碼

 ## Flutter 模塊的路徑
  flutter_application_path = '/Users/ly/Desktop/所有/項目/APP/fighting_flutter_common_user'
  eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')),    binding)
 

加完后，你的Podfile大概就是下面這個樣子的：

target 'fireCommonUser' do
  # Uncomment this line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
  # Pods for FireControl
  pod 'AFNetworking'
  pod 'AMapLocation'
  pod 'AMap2DMap'
  pod 'AMapSearch'
  pod 'MQTTClient'
  
  ## Flutter 模塊的路徑
  flutter_application_path = '/Users/ly/Desktop/所有/項目/APP/fighting_flutter_common_user'
  eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')),    binding)

  target 'fireCommonUserTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'fireCommonUserUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

• 可用如下命令更新Pod，會自動生成 flutter.framework

pod update --verbose --no-repo-update

• 增加編譯選項

打開iOS項目，選中項目的Build Phases選項，點擊左上角+號按鈕,選擇New Run Script Phase,將下面的shell腳本添加到輸入框中：

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed

具體如下：

結(jié)束

Pod集成到這里就結(jié)束了，真的很方便，F(xiàn)lutter 功能更新后，我這邊就一個 Pod update 就好了；

如果需在項目中調(diào)用Flutter模塊，并且跟Flutter進(jìn)行數(shù)據(jù)交互，比如，

• Flutter怎么獲取通訊錄權(quán)限；
• 獲取到的通訊錄以什么樣的格式傳遞呢

后面會專門整理一片文章介紹；

最后有問題歡迎大家留言討論；

如果你覺得文章對你有一點幫助，歡迎點個??，謝謝！
