如果您尚未启用 multidex，请转至

/android/app/build.gradle 并添加

multidrxEnabled true

在默认配置中

它应该是这样的：

defaultConfig {
            // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
            applicationId "com.example.chat_app_flutter_firebase"
            minSdkVersion 16
            targetSdkVersion 28
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

            //Enable multidex by adding this line 

            multiDexEnabled true
        }
