[SOLVED] Unhandled Exception: **GeminiException** => The connection errored:

Unhandled Exception: **GeminiException** => The connection errored:

I'm using flutter_gemini package in my project. Yesterday it worked for me, I could chat with the Gemini AI, but today I can't. It is strange, because I did not touch the code. I receive this error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: GeminiException => The connection errored: Failed host lookup: 'generativelanguage.googleapis.com' This indicates an error which most likely cannot be solved by the library.

This is how the Gemini is initialized:

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
  ]);
  Gemini.init(apiKey: kGeminiApiKey);
  runApp(const MyApp());

And this is how I use it in my StatefulWidget:

 gemini.streamGenerateContent(question, images: images).listen((event) {
        // logic goes here
      });

Why wont this work for me?

Solution

This error is due to Flutter's release mode not putting the INTERNET permission in the Android manifest. So, you have to do that manually.

Add this permission to your android/app/src/main/AndroidManifest.xml file

<uses-permission android:name="android.permission.INTERNET" />
