1、安裝flutter

cd /usr/local/

git clone -b master https://github.com/flutter/flutter.git

複製程式碼

• 1.1 加入環境變數

# 編輯配置檔案
vi ~/.profile 
# 在末尾加入
export PATH=/usr/local/flutter/bin:$PATH
# 儲存退出，終端中執行 
source ~/.profile
# 執行 flutter doctor 這個過程需要下載Dart SDK， 需要翻牆 否則會失敗
flutter doctor
複製程式碼

2、 科學上網

藍燈github地址,

# 安裝
sudo gdebi lantern-installer-64-bit.deb 
# 執行
lantern
複製程式碼

• 然後在執行 flutter doctor 進行檢測

  # 統一協議
  flutter doctor  --android-licenses
  複製程式碼

3、安裝android studio

3.1 首先要安裝32位依賴

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
複製程式碼

android 相關工具地址可以到這裡下載

3.2 安裝jdk

下載地址jdk-8u211-linux-x64.tar.gz

解壓縮 安裝

tar -zxvf jdk-8u211-linux-x64.tar.gz
mv jdk1.8.0_211/ /usr/lib/jvm/ 

vi ~/.profile
# 在最後插入：

export JAVAHOME=/usr/lib/jvm/jdk1.8.0_211
export CLASSPATH=.:$JAVAHOME/lib:$JAVAHOME/jre/lib:$CLASSPATH
export PATH=$JAVAHOME/bin:$JAVAHOME/jre/bin:$PATH

# 儲存退出，終端中執行 
    source ~/.profile
# 輸入: 
    java -version 
複製程式碼

3.3 安裝android sdk

SDK-TOOL 工具地址 sdk-tools-linux-4333796.zip

tar -zxvf android-sdk_r24.4.1-linux.tgz
mv android-sdk-linux/ /usr/local/android-sdk-linux/

vi ~/.profile
# 在最後插入：

export ANDROID_SDK_HOME=/usr/local/android-sdk-linux
export PATH=$PATH:${ANDROID_SDK_HOME}/tools
export PATH=$PATH:${ANDROID_SDK_HOME}/platform-tools

# 儲存退出，終端中執行 
    source ~/.profile
複製程式碼

3.4 下載 android studio

cd 下載
tar -zxvf android-studio-ide-183.5452501-linux.tar.gz 
sudo mv android-studio/ /usr/local/android-studio/
cd /usr/local/android-studio/
sh ./bin/studio.sh

複製程式碼

• 安裝完成後，會自動開啟android-studio，
  • 點選右下角的 configure下拉框，選擇plugins 輸入flutter 安裝外掛，重啟。
  • 點選 congigure 下拉框選擇 AVD MANAGER 建立一個模擬器。

4、測試

執行 flutter doctor

4.1 建立專案

在android studio起始頁點選 start a new flutter project 會出現假死，大概1分鐘左右，根據電腦效能決定時間長短。等待就好啦。

tmd，建立專案卡這裡啦，等了十分鐘啦。

建立 android studio 快捷方式 開啟 tools -> Create Desktop Entry

建立一個模擬器就可以正常開發啦

4.2 使用vscode進行開發

4.2.1 vs code中 安裝外掛 flutter

建立專案

flutter create demo01
複製程式碼

All done!
[✓] Flutter is fully installed. (Channel master, v1.5.9-pre.44, on Linux, locale

    SDK version 28.0.3)
[✓] Android Studio is fully installed. (version 3.4)
[✓] Connected device is fully installed. (1 available)

In order to run your application, type:

  $ cd demo01
  $ flutter run

Your application code is in demo01/lib/main.dart.

檢視模擬器列表

flutter emulator
複製程式碼

1 available emulator:

Nexus_5_API_26 • Nexus 5 • Google • Nexus 5 API 26

To run an emulator, run 'flutter emulators --launch <emulator id>'.
To create a new emulator, run 'flutter emulators --create [--name xyz]'.

You can find more information on managing emulators at the links below:

執行模擬器

flutter emulators --launch <模擬器ID>

執行專案

cd demo01/
flutter run

建立新的模擬器

flutter emulators --create [--name <模擬器ID>]
複製程式碼

# 建立
flutter emulators --create --name phone01
# 檢視
flutter emulators
# 結果
Nexus_5_API_26   • Nexus 5 • Google • Nexus 5 API 26

# 執行指定模擬器
flutter emulators --launch phone01

# 執行專案
flutter run 
# 給出提示

複製程式碼

• 看到模擬器頭部 有文字說明當前是哪一個

  

  知道是5556的這個所以繼續執行

flutter run -d emulator-5556
複製程式碼

接下來可以正常開發。
