如果您还没有启用multidex，请转到
/android/app/build.gradle并添加
multiDexEnabled true
默认配置
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
}
