Unable to build with prelease versions of amplify and amplify_authenticator #1258

Closed 94Sip closed 2 years ago

94Sip commented 2 years ago

Describe the bug I am trying to use the new amplify_authenticator. I have setup my pubspec.yaml file as shown below, and which seems to follow the documentation for the amplify_authenticator (https://pub.dev/documentation/amplify_authenticator/latest/). I have also tried to build by specifying 0.3.0-rc.3 for the amplify_* packages, which also is giving me the same error.

dependencies: amplify_auth_cognito: ^0.3.0-0 amplify_authenticator: ^0.1.0-0 amplify_flutter: ^0.3.0-0 amplify_datastore: ^0.3.0-0 amplify_analytics_pinpoint: ^0.3.0-0 amplify_storage_s3: ^0.3.0-0 amplify_api: ^0.3.0-0

when i goto 'Run>Start Debugging' in VS Code I get the following error: : Error: Error when reading '../../../../flutter/.pub-cache/hosted/pub.dartlang.org/amplify_flutter-0.3.0-rc.3/lib/amplify_flutter.dart': The system cannot find the file specified. (screen shot captured below)

The source of this error appears to be the way that amplify_authenticator.dart is trying to import amplify_flutter. Amplify_authenticator.dart appears to be using the "old" way by importing "amplify_flutter.dart", not amplify.dart, which is the only present in amplify_flutter package.

Hello @94Sip - Thanks for opening this issue. I was able to reproduce this. The latest release of the authenticator includes change to where Amplify is imported from, but the latest release of amplify_flutter does not include that change yet.

As a workaround until we get a new version of amplify_flutter released you can downgrade to amplify_authenticator: 0.1.0-rc.1. However, please be aware that there will be some changes in how you use the authenticator in rc.1. See below for details. Also note that rc.1 does not include this fix for navigation.

RC.1 Use

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Authenticator Demo',
      home: Authenticator(
        child: const Scaffold(
          body: Center(
            child: Text('You are logged in!'),
          ),
        ),
      ),
    );
  }

RC.2 Use

  @override
  Widget build(BuildContext context) {
    return Authenticator(
      child: MaterialApp(
        title: 'Authenticator Demo',
        builder: Authenticator.builder(),
        home: const Scaffold(
          body: Center(
            child: Text('You are logged in!'),
          ),
        ),
      ),
    );
  }

@Jordan-Nelson Thank you Jordan - i was going a bit crazy thinking I had somehow corrupted my pub-cache.

To be clear, should I use rc.1 or rc.2? I read the linked fix thread, which highlights the documentation here, which appears to be rc.2

I'm more than willing to change because I don't think either of these will be a problem for me.

Jordan-Nelson commented 2 years ago

@94Sip right now you will need to use the following dependencies:

amplify_flutter: ^0.3.0-rc.3
amplify_auth_cognito: ^0.3.0-rc.3
amplify_authenticator: ^0.1.0-rc.1

And to use the Authenticator, the code in your app will look like 

@override
Widget build(BuildContext context) {
  return MaterialApp(
    title: 'Authenticator Demo',
    home: Authenticator(
      child: const Scaffold(
        body: Center(
          child: Text('You are logged in!'),
        ),
      ),
    ),
  );
}

We are hoping to get a new release of amplify_flutter/amplify_auth_cognito that will allow you to switch back to the latest version of the amplify_authenticator.

Jordan-Nelson commented 2 years ago

New RC versions of all the libraries were released today. You can update to those versions now.

For the Authenticator, you will want to use the following dependencies:

  amplify_flutter: 0.3.0-rc.4
  amplify_auth_cognito: 0.3.0-rc.4
  amplify_authenticator: 0.1.0-rc.3

Two things to note:

  1. You likely have an import statement of import 'package:amplify_flutter/amplify.dart'; in at least one location in your app. You will need to update this to import 'package:amplify_flutter/amplify_flutter.dart';. This was a breaking change introduced in 0.3.0-rc.4.
  2. If you downgraded to RC.1 and followed the code snippet that I shared above, you will now need to go back to the other format. It should just be minor changes. See example below, or refer to the authenticator docs. 
    @override
Widget build(BuildContext context) {
return Authenticator(
  child: MaterialApp(
    title: 'Authenticator Demo',
    builder: Authenticator.builder(),
    home: const Scaffold(
      body: Center(
        child: Text('You are logged in!'),
      ),
    ),
  ),
);
}

I am going to close this issue out. Thanks again for opening it and bringing it to our attention @94Sip

thank you very much!

94Sip commented 2 years ago

@Jordan-Nelson I was able to get everything working - thank you.

One note: I had to go in to amplify CLI, and run 'amplify pull' to update my amplifyconfiguration.dart because this version of Authenticator expects there to be a usernameAttributes section in Auth configuration. For whatever reason, the previous of version of amplify CLI did NOT include this attribute. The error that was thrown explained this but I'm mentioning this because perhaps it is helpful as you move closer to a release, or you might want to include this in the documentation.
