# Flutter - 改變APP名稱及Icon

## 更改名稱
### Android

<application
        android:label="與原生"
        android:name="${applicationName}"


### IOS
Info.plist

<key>CFBundleDisplayName</key>
<string>與原生</string>
<key>CFBundleName</key>
<string>與原生</string>

## 更改Icon
1. 利用[線上工具](https://icon.kitchen/i/H4sIAAAAAAAAA6tWKkvMKU0tVrKqVkpJLMoOyUjNTVWySkvMKU6t1VHKzU8pzQHJRisl5qUU5WemKOkoZeYXA8ny1CSl2FoApT8%2BHkAAAAA%3D)生成APP圖片，並將圖檔下載
2. 將圖片放入資料夾`assets/icons/app.png`
3. 安裝flutter套件

    flutter pub add flutter_launcher_icons --dev

4. 調整設定檔`pubspec.yaml`

    flutter_launcher_icons:
      android: "launcher_icon"
      ios: true
      remove_alpha_ios: true
      image_path_android: "assets/images/app_logo.png"
      image_path_ios: "assets/images/app_logo.png"

5. 執行指令套用icon

    flutter pub run flutter_launcher_icons:main

## 抱錯
### Cannot not find minSdk from android/app/build.gradle
調整minSdkVersion即可，[參考資料](https://github.com/fluttercommunity/flutter_launcher_icons/issues/371)

### Images can't contain alpha channels or transparencies
ios 手機不可使用含有透明背景的圖示
#### 解決方法
使用 Mac 開啟圖片 > 檔案 > 屬性，把 alpha 的勾勾移除，點擊儲存即可
