我有一个流畅的应用程序运行良好,然后我想将所有插件升级到androidX,在我决定添加firebase_messaging之前,一切都运行良好,我尝试了4,5版,但没有任何效果,继续抛出该错误错误,好像我使用了错误的版本。而且我也尝试flutter packages pub cache repair
不走运。 github上有很多相关的问题,但是由于人们仍然抱怨该修复程序不起作用,它们都被关闭了。
这是我的gradle像
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '3'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0.1'
}

以下更改解决了我的问题
来自:
ext {
firebaseMessagingVersion = "+" // default: "+"
}
到:
ext {
firebaseMessagingVersion = "21.1.0"
}

是的,因为 com.google.firebase.iid.InstanceIdResult 已弃用且不再可用。 因此,为了从 firebase 获取令牌,您现在必须使用。
FirebaseMessaging.getInstance().getToken()
.addOnCompleteListener(new OnCompleteListener<String>() {
@Override
public void onComplete(@NonNull Task<String> task) {
if (!task.isSuccessful()) {
Log.w(TAG, "Fetching FCM registration token failed", task.getException());
return;
}
// Get new FCM registration token
String token = task.getResult();
// Log and toast
String msg = getString(R.string.msg_token_fmt, token);
Log.d(TAG, msg);
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});

我能够使用此确切版本的gradle和google-services版本号组合来解决此问题,希望它能对您有帮助
