flutter - local_auth

孤浪王者

背景

  指纹辨认，援用local_auth库，iOS一般利用，安卓机器上发明报错，内乱容以下：
Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)

打点法子

1. 增加USE_FINGERPRINT权限

1. <!-- AndroidManifest.xml -->
2. <uses-permission android:name="android.permission.USE_FINGERPRINT"/>

复造代码

2. FlutterActivity -> FlutterFragmentActivity

1. // MainActivity.kt
2. class MainActivity: FlutterFragmentActivity() {
3.     override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
4.         GeneratedPluginRegistrant.registerWith(flutterEngine)
5.     }
6. }

复造代码

3. Theme.AppCompat 成绩

假如报如许的错：If you receive this error: Exception has occurred. PlatformException (PlatformException(error, You need to use a Theme.AppCompat theme (or descendant) with this activity., null))，能够需求如许做：

• 找到android>app>src>main>res>values>style.xml文件
  
• 把 交换成
