配置
基本配置成功是這樣的。
image.png
可以看到其實需四部分東西：
1、二進制，我們使用穩定版1.22.x。具體參照 https://flutter.cn/docs/get-started/install/macos
2.工具鏈，android和iOS兩個系統的工具鏈
3.IDE Android Studio及flutter/dart插件
4.調試模擬器
Mac中最常見的問題就是和android相關的
一、flutter和dart的插件找不到，明明已經下載了，就是報錯
image.png
這是因為Android Studio (4.1) 的插件位置換成了
~/Library/Application\ Support/Google/AndroidStudio4.1/plugins，而老版本的位置為~/Library/Application\ Support/AndroidStudio4.1
需要執行一個軟鏈
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
二、android sdk的版本和platform tool的版本提示錯誤
Flutter requires Android SDK 29 and the Android BuildTools 28.0.3 To update the Android SDK visit
image.png
這個有兩個可能的原因:
1、確實沒有安裝android sdk和platform-tool的包
切記，要勾選show package details選項框，才會顯示出所有版本號。
image.png
2、PATH沒有配置對
android studio下載的路徑是Android SDK location對應的路徑，而flutter doctor 檢測的路徑是環境變量PATH,此二者務必對應上！
image.png

這是flutter doctor遇到的兩個主要坑
三、運行問題
Android問題
1.android跑不起來，Gradle threw an error while trying to update itself.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
Running Gradle task 'assembleDebug'...
Exception in thread "main" java.util.zip.ZipException: error in opening zip file

at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61)
[!] Gradle threw an error while trying to update itself. Retrying the update...
這個的原因是gradle的版本問題，需要把系統中的gradle版本刪掉，然后run的時候自動下載一個就可以了
/Users/用戶名/.gradle/wrapper/dists/gradle-5.6.2-all
或者也可以下載文件放到這個目錄中，把之前的替代了
https://downloads.gradle-dn.com/distributions/gradle-5.6.2-all.zip
2、安卓跑不起來, io.flutter問題

這些跑不起來真機或模擬器的case,報一些io.flutter.xxx的問題，基本是因為倉庫源下不下來。
解決方法：
1、在android/build.gradle中將google() jcenter()刪掉，換成aliyun的倉庫，外加一個download.flutter.io
2、在$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"中同樣
buildscript {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
maven { url 'http://download.flutter.io' }
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
}
}
allprojects {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
maven { url 'http://download.flutter.io' }
}
}
buildscript {

}
安卓gradle插件和版本對應關系

|---|---|
| 1.0.0 - 1.1.3 | 2.2.1 - 2.3 |
| 1.2.0 - 1.3.1 | 2.2.1 - 2.9 |
| 1.5.0 | 2.2.1 - 2.13 |

3.gradle問題
gradle是個人最深惡痛絕的一個東西，先吐為快！
首先他有gradle版本和插件的配套問題，和上面的圖標一致。其次它自身很大，更新頻繁，向下兼容性差，需要翻墻。
好了，言歸正傳。
每次編譯都下載gradle-x.x-all.zip gradle-x.x.zip。每次都下不下來，等的想砸電腦。
解決方法：
1、環境變量里配置
export GRADLE_HOME=/usr/local/Cellar/gradle/wrapper/dists/gradle-6.1.1-all
export PATH=$PATH:${GRADLE_HOME}/bin
2、gradle-wrapper.properties中修改distributionUrl為file:///usr/local/Cellar/gradle/wrapper/dists/gradle-6.8.1-all.zip
distributionUrl=file:///usr/local/Cellar/gradle/wrapper/dists/gradle-6.8.1-all.zip
這個文件是
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip
distributionUrl=file:///usr/local/Cellar/gradle/wrapper/dists/gradle-6.8.1-all.zip
GRADLE_USER_HOME對應的是preferences里Build,Execution,Deployment中Gradle下的General settings下的Gradle user home。
distributionPath對應的是這個目錄下的某一個目錄。
zipStoreBase和zipStorePath顧名思義就是zip包的存儲位置
distributionUrl是zip包的來源，默認是從https://services.gradle.org/distributions拿，我們改成從一個本地目錄拿。
修改完之后，執行flutter clean flutter run --verbose即可看到不在downloading.
緊接著，你會遇到另一個問題，
卡在Starting a Gradle Daemon (subsequent builds will be faster)
解決方法：
切換網絡，直到它開始執行。時間會長一些。

Starting a Gradle Daemon, 2 busy Daemons could not be reused, use --status for details
關掉精靈進程可以用 gradle stop他會告訴你 No Gradle daemons are running. 但是仍然會卡住。
Starting a Gradle Daemon, 2 stopped Daemons could not be reused, use --status for details
gradle --status
PID STATUS INFO
61498 IDLE 6.8.1
59750 STOPPED (stop command received)
57879 STOPPED (by user or operating system)
卡住的原因是同步的，需要在gradle全局配置中設置為支持并行
解決方法：
/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)
在如上目錄中找到gradle.properties(沒有就創建一個)
加上下面兩句
org.gradle.daemon=true
org.gradle.parallel=true
iOS問題
1.iOS真機無法打開“iproxy”，因為無法驗證開發者。
無法打開“ idevice_id”，因為無法驗證開發者。
無法打開“ idevicename”，因為無法驗證開發者。
無法打開“ idevicescreenshot”，因為無法驗證開發者。
無法打開“ idevicesyslog”，因為無法驗證開發者。
無法打開“ ideviceinfo”，因為無法驗證開發者。
這都是一類問題
執行如下命令，就可以了。
sudo spctl --master-disable
sudo xattr -r -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/libimobiledevice/idevice_id
sudo xattr -r -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/libimobiledevice/idevicename
sudo xattr -r -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/libimobiledevice/idevicescreenshot
sudo xattr -r -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/libimobiledevice/idevicesyslog
sudo xattr -r -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/libimobiledevice/ideviceinfo
sudo xattr -d com.apple.quarantine {flutter目錄}/bin/cache/artifacts/usbmuxd/iproxy
2、iOS<Flutter/Flutter.h>文件找不到問題
/Users/hyf/develop/ios/demos/AI/f_ai/.ios/Flutter/FlutterPluginRegistrant/Classes/GeneratedPluginRegistrant.h:8:9: 'Flutter/Flutter.h' file not found
需要flutter版本和cocoapods版本對應，1.22版本需要和cocoapods1.10.x匹配。
執行sudo gem install cocoapods，刪除Podfile.lock，然后執行pod install即可。
這個坑歷史版本也出現過。比如flutter0.2.x必須匹配cocoapods1.4 https://github.com/flutter/flutter/issues/16036,總之，flutter doctor中建議你用什么版本就用什么版本，千萬不要相信它的兼容性。
3、flutter Waiting for iPad to report its views
從master更換到stable之后，一直就跑不起來。報這個錯，屏幕白屏，卡在那里。
需要 flutter clean 再 flutter run
四、更新相關
對web的支持是在beta channel中的。stable channel暫未支持。
切換channel使用flutter channel stable和flutter channel beta,穩定性上stable要比beta高的多，但beta代碼要新的多.beta分支上，不僅flutter的代碼是beta的，連依賴也是beta的，如dart
比如
>flutter upgrade
Flutter is already up to date on channel beta
Flutter 1.25.0-8.3.pre ? channel beta ? https://github.com/flutter/flutter.git
Framework ? revision 5d36f2e7f5 (6 天前) ? 2021-01-14 15:57:49 -0800
Engine ? revision 7a8f8ca02c
Tools ? Dart 2.12.0 (build 2.12.0-133.7.beta)
官方建議要使用package,不要使用pub. 不明白這兩個有啥區別，麻煩知道的大大們留言告知一下。
不要使用pub get或pub upgrade命令來管理你的依賴關系。相反，應該使用flutter packages get或flutter packages upgrade。如果您想手動使用pub，則可以通過設置FLUTTER_ROOT環境變量來直接運行它。
五、倉庫
.gitignore的生成
1、標準化：https://www.toptal.com/developers/gitignore
2、前輩實踐：https://github.com/flutter/flutter/issues/13892
