Recently, I studied using firebase in a flutter project. I followed the step but also got an error. I searched and guess it is a app\build.gradle getting a problem. But also didn't know what the problem is.

No signature of method: build_5viubdggwtiixi0imz59oppqn.android() is applicable for argument types: (build_5viubdggwtiixi0imz59oppqn$_run_closure2) values: [build_5viubdggwtiixi0imz59oppqn$_run_closure2@71088475] Here are the "relevant codes and error:

Error:

@lousea, We get such kind of error when we use any undefined attribute in the gradle file.

In your case, in the default config, you have misspelled the multidex attribute. Just change MultiDexEnable to multiDexEnabled then it will work properly. or just replace the defaultConfig from below

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.getx.app.db.firebaseApp"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }
