Hi @shodgetts thank u for replying, I am trying to run the example folder provided in this git repo.
Let me described what I did.

I got API Key from Stream dashboard, I replace in file bellow : main.dart

final client = Client(
    'my-api-key',
    logLevel: Level.INFO,
    showLocalNotification: Platform.isAndroid ? showLocalNotification : null,
    persistenceEnabled: true,
  );

  await client.setUser(
    User(id: 'super-band-9'),
    'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoic3VwZXItYmFuZC05In0.0L6lGoeLwkz0aZRUcpZKsvaXtNEDHBcezVTZ0oPq40A',
  );

when I run using this command: flutter run -d all it did run, but I receive this 401 error stated that received new event: {"error":{"code":43,"message":"Connect failed with error: \"JWTAuth error: signature is not valid. Make sure the token is created using the secret for API key \"tv8e7chkfsr7\"\"","StatusCode":401,"duration":"0.00ms"}}

My question is where should I generate a token (how to generate this token). I do not have any back end yet.

Hi

You can generate your token using this code. This is in JS though.

const test = async () => {
    const client = new StreamChat(
      "api_key",
      "api_secret",
      { timeout: 3000 }
    );

    const token = await client.createToken("User_id");

Cheers

Hi @shodgetts
Error : StreamChat not not accepting args as String, it accepting arg as widget and Client ! StreamChat(child: widget, client: client,)

new StreamChat(
      "api_key",
      "api_secret",
      { timeout: 3000 }
    )

Hi @veyhong
It's not possible to create the token using the SDK, you should create it server-side (https://getstream.io/chat/docs/tokens_and_authentication/?language=dart)
For development you can also use our token generator (https://getstream.io/chat/docs/token_generator/?language=dart)

Thanks @imtoori and @shodgetts , it work now.
