Answer 1

Make sure you are using the latest cloud_firestore version. Then execute:

flutter clean
flutter packages get

---

Update, Starting since cloud_firestore version 0.14.0:

setData() was replaced with set() . Other useful link:

The getter 'instance' isn't defined for the type 'Firestore'

Answer 2

for my case, I performed steps as below:

flutter clean
flutter packages get

uninstall app

update: /android/app/build.gradle

defaultConfig {
    ...
    multiDexEnabled true
}

run again.

hope this helps

I closed the IDE (Android Studio) and did flutter clean . After that I restarted the IDE and created a new AVD. The MissingPluginException was gone after that and I had the following error:

D8: Cannot fit requested classes in a single dex file

I fixed this adding multiDexEnabled true to the defaultConfig in /android/app/build.gradle

defaultConfig {
    ...
    multiDexEnabled true
}

I don't know if this is releated to your problem, but thats how I solved the error.

Answer 4

My problem was caused by editing the firebase instance settings after I've used the firestore in the previous page which u can't do and it didn't give me the correct error for it until I delete this folder

%AppData%\Local\Pub\Cache\hosted\pub.dartlang.org\firebase_core_platform_interface-2.0.0

and then It correctly gave me the error and so I just applied the settings in main.dart

Widget build(BuildContext context) 
{
   return FutureBuilder(
      future: Firebase.initializeApp(),
      builder: (context, snapshot) 
      {
         if (snapshot.hasError) {
            return Text('error');
         }

         if (snapshot.connectionState == ConnectionState.done) {
            FirebaseFirestore.instance.settings = Settings(
            persistenceEnabled: true,
            cacheSizeBytes: Settings.CACHE_SIZE_UNLIMITED,
            );

          return MaterialApp(....
         }
      }
   );
}

Answer 5

Stop the running app and rerun. It may be because you added the firestore dependency while the app is already running in debug mode. In this case the hot reload or restart will not work if you to call methods of newly added dependency. You have to stop the running app and rerun. (This solved my issue).

Do this before rerunning. - flutter clean - flutter packages get

Answer 6

If you are working on Visual Studio Code and you are running your project on an IOS simulator, then it might not work. You can run your project from Xcode and it will work with no issues, you have to open the file that is .xcworkspace.

Answer 7

I tried this and it helped me

flutter clean
flutter packages get

Later, Uninstall App and try reinstalling it ✌🏻
