TOC

Flutter安裝

• 操作系統: windows7以上64位操作系統
• 磁盤空間：大於3G,最好可以達到5G
• 安裝java
• 安裝flutter sdk
• 虛擬機

安裝flutterSDK

安裝

• 方法1:https://flutter.dev/docs/development/tools/sdk/releases#windows
  
  • 下載的是壓縮包,在安裝位置解壓;
• 方法2:git:

https://github.com/flutter/flutter.git
國內鏡像地址:
https://mirrors.tuna.tsinghua.edu.cn/git/flutter-sdk.git
碼雲https://gitee.com/mirrors/Flutter的:https://gitee.com/mirrors/Flutter.git

建議:
使用碼雲的git
使用分支:stable

配置環境變量

• path:將flutter的bin地址添加到環境變量的path中;
• 添加flutter鏡像等配置FLUTTER_STORAGE_BASE_URL和PUB_HOSTED_URL;

中國庫

FLUTTER_STORAGE_BASE_URL:https://storage.flutte-io.cn
PUB_HOSTED_URL:https://pub.flutter-io.cn

清華

PUB_HOSTED_URL:https://mirrors.tuna.tsinghua.edu.cn/dart-pub
FLUTTER_STORAGE_BASE_URL:https://mirrors.tuna.tsinghua.edu.cn/flutter

上海交通大學

FLUTTER_STORAGE_BASE_URL:https://mirrors.sjtug.sjtu.edu.cn
PUB_HOSTED_URL:https://dart-pub.mirrors.sjtug.sjtu.edu.cn

我最終選擇的是

PUB_HOSTED_URL:https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL:https://mirrors.sjtug.sjtu.edu.c

安裝配置

• 雙擊運行安裝路徑/bin/flutter.bat
• 運行檢查

flutter doctor

• 沒有X之后運行

flutter doctor --android-licenses

一直輸入y,完成配置

• 修改鏡像:flutter\packages\flutter_tools\gradle\flutter.gradle

buildscript {
    repositories {
// google()
// jcenter()
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 "https://storage.googleapis.com/download.flutter.io" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }
}

每一個項目配置

buildscript {
    repositories {
// google()
// jcenter()
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 "https://storage.googleapis.com/download.flutter.io" }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'  //這個版本號看自己的配置
    }
}

allprojects {
    repositories {
// google()
// jcenter()
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 "https://storage.googleapis.com/download.flutter.io" }
    }
}

升級flutter

升級

• 方法1:flutter upgrade
• 方法2:刪除舊的sdk,重新下載

配置

• 雙擊運行安裝路徑/bin/flutter.bat
• 運行檢查

flutter doctor

注意:flutter升級之后,有的項目就無法正常運行了,建議在項目根目錄使用flutter clean清除配置,然后使用flutter pub get重新配置一下

vscode搭建環境

安裝Dart/Flutter/Flutter Widget Snippets /Awesome Flutter Snippets/Android ios Emulator插件;

vscode創建項目

進入需要創建項目的文件夾

運行

flutter create 項目名

(可能需要安裝cmake)

運行

普通運行

使用vscode打開項目文件夾,在終端輸入flutter run,這種模式不能熱加載,需要在命令行輸入相應字符才能操作

操作

R:重啟並熱加載
r:熱加載
h:幫助
d:分離
q:退出
p:顯示網格,這個可以很好的掌握布局情況,工作中很有用。
o:切換android和ios的預覽模式。
q:退出調試預覽模式。

熱加載debugger

左側選擇debugger的中的運行即可.

連接第三方模擬器

第三方模擬器需要開啟root權限,若是有usb調試選項,也要開啟

cmd進入Android sdk的platform-tools文件夾,運行adb連接代碼

夜神模擬器：adb connect 127.0.0.1:62001

逍遙安卓模擬器：adb connect 127.0.0.1:21503

天天模擬器：adb connect 127.0.0.1:6555

海馬玩模擬器：adb connect 127.0.0.1:53001

網易MUMU模擬器：adb connect 127.0.0.1:7555

原生模擬器：adb connect (你的IP地址)：5555

mumu:adb connect 127.0.0.1:7555

異常

啟動異常Initialization gradle…

如果啟動過程中一直卡在 Initialization gradle…

那就去gradle官網下載他的zip壓縮包 然后放在.gradle\wrapper\dists\gradle-4.10.2-all\9fahxiiecdb76a5g3aw9oi8rv下 把其他文件刪除
gradle的版本要對應好

adb 提示adb server version(31) doesn't match this client（40）

adb的版本沖突問題,

1. 將AndroidSDK的platform-tools和cmdline-tools和build-tools路徑添加到path中,重啟虛擬機(重連手機),重啟Android SDK軟件(最好重啟軟件),測試一下;
2. 若是還有問題,可能是電腦之前安裝過adb的服務,打開windows管理工具中的服務,看看有沒有adb的,把這個服務停止(最好禁用了,不然每次都要停止一下),測試一下;
3. 可能是端口沖突,這是因為你的電腦安裝了，魯大師手機助手，360手機助手占用了adb的端口引起的。
   
   1. cmd輸入netstat -ano|findstr “5037”,去查找5037對應的端口號的進程id 也就是pid。如果有相應的pid，就證明此端口5037有程序占用了
      

      

   2. 輸入tasklist |findstr “15828”,看到占用端口的軟件,去吧這個軟件停了
      
      1. 任務管理器的詳細信息可以看到,右鍵結束即可(可以按照名字查找或者在表頭右鍵顯示pid,找到對應pid的程序);
      2. 使用代碼強制結束:taskkill /pid 15828 -t -f

      

flutter安裝dart失敗:

打開flutter目錄\bin\internal
打開engine.version
下載文件

https://mirrors.sjtug.sjtu.edu.cn/flutter_infra/flutter/文件內容/dart-sdk-darwin-x64.zip

下載的dart文件,解壓,添加bin目錄到path環境變量

添加環境變量FLUTTER_STORAGE_BASE_URL,值為https://mirrors.tuna.tsinghua.edu.cn(注意不要有后面的\flutter)

Could not resolve io.flutter:flutter_embedding_debug:1.0.0-6bc433c6b6b5b98dcf4cc11aff31cdee90849f32

進入flutter\packages\flutter_tools\gradle 目錄下

• aar_init_script.gradle
• resolve_dependencies.gradle
• flutter.gradle

將http://download.flutter.io 替換為: https://storage.googleapis.com/download.flutter.io

將
google()
jcenter()
替換為:
// google()
// jcenter()
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 "https://storage.googleapis.com/download.flutter.io" }

下載包失敗:Could not resolve all artifacts for configuration....

flutter在下載依賴失敗或者flutter run運行的時候出現某個jar或者文件下載失敗的時候,如下:

解決方法:將鏡像依賴下載地址改為國內地址
```shell
將
google()
jcenter()

改為:

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 "https://storage.googleapis.com/download.flutter.io" }
google()
jcenter()
````
需要修改的位置:

• 當前項目:android/build.gradle
• fluttersdk:flutter安裝位置\packages\flutter_tools\gradle里的flutter.gradle和resolve_dependencies.gradle
• 下載失敗的鏡像(比如上面的是url_launcher):在flutter安裝位置\.pub-cache\hosted\當前倉庫\android\build.gradle

注意:上面的配置有的文件中有一處,有的有兩處
