I am using flutter, in Android Studio.
I am getting this in my console:
W/Firestore(26053): (24.2.2) [OnlineStateTracker]: Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds
W/Firestore(26053):
W/Firestore(26053): This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
E/flutter (26053): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: [cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

W/Firestore(26053): (24.2.2) [WatchStream]: (a4a9ed6) Stream closed with status: Status{code=UNAVAILABLE, description=Channel shutdownNow invoked, cause=null}.
I have tried:
- put
<uses-permission android:name="android.permission.INTERNET" />
in all 3 AndroidManifest.xml files - put
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
in AndroidManifest.xml under main - Enabled Multidex
- Used a different wifi connection
- Checked back the second day with the same issue
- My minimum SDK version is 21
- Copied my code to a fresh new project
Here is my main function:
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(
name: 'Retrospect',
options: DefaultFirebaseOptions.currentPlatform,
);
runApp(MyApp());
}
I should be initializing the app correctly, because I get his in my console:
I/FirebaseApp(26053): Device unlocked: initializing all Firebase APIs for app Retrospect
I/flutter (26053): Refreshing
W/DynamiteModule(26053): Local module descriptor class for com.google.android.gms.providerinstaller.dynamite not found.
I/DynamiteModule(26053): Considering local module com.google.android.gms.providerinstaller.dynamite:0 and remote module com.google.android.gms.providerinstaller.dynamite:0
W/ProviderInstaller(26053): Failed to load providerinstaller module: No acceptable module com.google.android.gms.providerinstaller.dynamite found. Local version is 0 and remote version is 0.
The problem could be caused by the line W/DynamiteModule(26053): Local module descriptor class for com.google.android.gms.providerinstaller.dynamite not found.
, that I was also unable to resolve.
Here are my pubspec.yaml file dependencies:
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^1.0.2
firebase_core: ^1.20.1
cloud_firestore: ^3.4.4
http: ^0.13.4
path_provider: ^2.0.11
get_storage: ^2.0.3
I believe that I am using the latest versions of firebase_core and cloud_firestore.
My app/build.gradle file dependencies and plugins:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'com.google.gms.google-services'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "com.android.support:multidex:1.0.3"
implementation 'com.google.android.material:material:1.6.1'
implementation 'com.google.android.gms:play-services-ads:21.1.0'
implementation platform('com.google.firebase:firebase-bom:30.3.2')
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation 'com.google.firebase:firebase-storage-ktx'
}
My build.gradle file:
buildscript {
ext.kotlin_version = '1.6.10'
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:7.1.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.13'
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}
google-services.json file location:
Here are my rules in Firestore (rules should not be the problem because I was able to successfully read data using python.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2022, 12, 12);
}
}
}
Finally, here is the function I call:
import 'package:cloud_firestore/cloud_firestore.dart';
Future<bool> checkIfDocExists(String docId) async {
try {
// Get reference to Firestore collection
var collectionRef = FirebaseFirestore.instance.collection('accounts');
var doc = await collectionRef.doc(docId).get();
return doc.exists;
} catch (e) {
throw e;
}
}
What causes this error? (I am unable to access Cloud Firestore at all through flutter).
I did not see my antivirus (Windows Defender) or Firewall block anything, but I can provide the logs if needed.

Thanks to @Damian for the solution!
The problem was the emulator, not the code itself

How to continue with this issue:

invocation.Enabling appcheck on the app helped solve the problem on my end
Switching the emulator’s or device’s internet connection to a stronger alternative fixed it.
