Application.kt：未解决的参考：firebasemessaging

html5 • • 问答

我正在尝试更新firebase_messaging到新版本8.0.0-dev.10。

但是，我收到以下错误：

Running Gradle task 'assembleDebug'...
Application.kt: (5, 27): Unresolved reference: firebasemessaging
Application.kt: (6, 27): Unresolved reference: firebasemessaging
Application.kt: (11, 9): Unresolved reference: FlutterFirebaseMessagingService
Application.kt: (15, 9): Unresolved reference: FirebaseMessagingPlugin

Running Gradle task 'assembleDebug'...
Application.kt: (5, 27): Unresolved reference: firebasemessaging
Application.kt: (6, 27): Unresolved reference: firebasemessaging
Application.kt: (11, 9): Unresolved reference: FlutterFirebaseMessagingService
Application.kt: (15, 9): Unresolved reference: FirebaseMessagingPlugin

这就是我的 Application.kt 的样子

有任何想法吗？

您可以按如下方式修复它，创建Application.kt文件

package com.example.YOUR.PACKAGE

import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry

import io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingPlugin

class Application() : FlutterApplication(), PluginRegistry.PluginRegistrantCallback {
  override fun registerWith(registry: PluginRegistry?) {
      val key: String? = FlutterFirebaseMessagingPlugin::class.java.canonicalName
      if (!registry?.hasPlugin(key)!!) {
          FlutterFirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingPlugin"));
        }
    }
}

并在您的清单中更改为：

 <application
        android:label="El Chaski Customer"
        android:name=".Application"
        android:icon="@mipmap/launcher_icon">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
......

https://firebase.flutter.dev/docs/messaging/overview/根据这个，如果你使用的是Flutter 1.12及更高版本，你不需要创建application.kt，并在manifest.xml中配置它，它开箱即用。

以上是Application.kt：未解决的参考：firebasemessaging的全部内容。
