[amplify_flutter] Support using `--wasm` flutter cli argument.

[asaarnak]

Because amplify_flutter is using Platform.isAndroid.

This is thrown: Unsupported operation: Platform._operatingSystem

Line: call $Platform.isAndroid

  (func $new AmplifyClassImpl (;33855;) (result (ref $AmplifyClassImpl))
    block $label1
      block $label0
        call $Platform.isAndroid implicit getter
        br_if $label0
        call $Platform.isIOS implicit getter
        i32.eqz
        br_if $label1
      end $label0
      call $AmplifyHybridImpl
      return
    end $label1
    call $AmplifyClassImpl.protected
    return
  )

The pub.dev suggests removing dart:io import from: package:amplify_flutter/amplify_flutter.dart package:amplify_flutter/src/amplify_impl.dart

Hi @asaarnak, thank you for raising this issue, along with a PR! Please see the discussion on that thread, we appreciate community contribution! We will track this as a feature request

[asaarnak]

Hi @ekjotmultani. I added an comment under the PR. Thanks.

I found the same issue with other packages while testing. The amplify_auth_cognito has same errors.

[asaarnak]

@tyllark After these commits the application is starting and loading first page.

But when i try to login i get some errors about worker on this line:

await Amplify.Auth.signIn(
  username: email,
  options: const SignInOptions(
    pluginOptions: CognitoSignInPluginOptions(
      authFlowType: AuthenticationFlowType.customAuthWithoutSrp,
    ),
  ),
);

Its looking for a file workers.debug.dart.js but can't find it, also when running with --release tag then its looking for a file workers.release.dart.js and also it's looking it from packages/amplify_auth_cognito_dart and also from test/packages/amplify_auth_cognito_dart directory.

Hello @asaarnak, sorry for the delay this issue has been a bit of a roller coaster for me. I started off migrating your changes to use os_detect as we already use that package in our repo and because defaultTargetPlatform would require modifications to all of our tests:

In a test environment, the platform returned is TargetPlatform.android regardless of the host platform.

I then realized that all of our references to dart:io were guard by a kIsWeb check or conditional imports, otherwise our non-wasm web builds would be failing. Well it ends up the way the Flutter team checks if they are running on the browser changed when wasm was released from

identical(0, 0.0);

to

bool.fromEnvironment('dart.library.js_interop');

You can see an example of this change in packages/flutter_test/lib/src/platform.dart in this Flutter team commit. Anyways we have the old method hardcoded into Amplify Flutter here, which means we are not guarding dart:io on wasm builds properly. I updated the check in this PR.

I reproduced the Unsupported operation: Platform._operatingSystem error without the fix and confirmed that the application is able to launch on my side with the fix! Unfortunately I'm getting the following MIME errors which seems to be breaking our Auth API on WASM:

Refused to execute script from 'http://localhost:57891/test/packages/amplify_auth_cognito_dart/src/workers/workers.debug.dart.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

I'm still working to get this unblocked, but wanted to give you an update. You can verify the changes so far with the following dependency override:

dependency_overrides:
  aws_common:
    git:
      url: https://github.com/aws-amplify/amplify-flutter.git
      ref: chore/update-zisweb
      path: packages/aws_common

@tyllark I tested with your branch, application now start and the other issue exists. Here are the logs, we also use soloud that also initializes Web Worker successfully, if it helps.

@tyllark If it helps, but this is my build folder. The workers.debug.dart.js file doesn't exist in build folder. Also the /packages/ maybe should be /assets/packages/?

[asaarnak]

And when building without the --wasm its in correct /packages/ folder.

[asaarnak]

And with the soloud we also needed to add these lines to our index.html.

  <script src="assets/packages/flutter_soloud/web/libflutter_soloud_plugin.js" defer></script>
  <script src="assets/packages/flutter_soloud/web/init_module.dart.js" defer></script>

[asaarnak]

@tyllark Did you have time to take a look at this worker.js issue?

[tyllark]

Hello @asaarnak, I've been working to update the build process on our end so we can properly generate/load the new WASM files produced by build_web_compilers. So far I've updated our code generation tools and Auth Cognito to support the new files, but I've ran into a few roadblocks along the way. I've been modifying my .pub-cache locally as a work around, but there are 2 Flutter team packages that I need to reach out to for updates.

1. crypto is conditionally importing web code but they are using previous non-wasm compatible libraries in the check.
2. build_web_compilers generates the JS mapping file workers.debug.dart2js.js.map as expected, but the dart2js_archive_extractor post process builder that extracts this file is not emitting the map file to other Builders.

Once those are addressed I still need to:

1. Migrate the remaining build.yaml files to support WASM
2. Extensive testing for all categories
3. Update Github Actions to test WASM builds

[asaarnak]

@tyllark I was wondering if there are any crypto or build_web_compilers issue yet that i could follow? We are waiting for the --wasm support and would be cool the see the progress.

[tyllark]

Hello @asaarnak, Ill create the issues today and Ill reply back here with the links.

[tyllark]

@asaarnak I've created the Crypto and build_web_compilers issues. Once we hear back from them we can unblock our WASM task!

Update: Crypto changes have been merged!

[asaarnak]

@tyllark Seems that we are now waiting for the crypto release only. Can we already test this?

[tyllark]

Hello @asaarnak, I've updated to build_web_compilers: ^4.3.2 and I'm locally using a dependency override for crypto:

dependency_overrides:
  crypto:
    git:
      url: https://github.com/dart-lang/core.git
      ref: main
      path: pkgs/crypto

amplify_auth_cognito_dart is now able to build for web and it is producing the correct output files, so I'll mark this task as unblocked and will look to pick it up in the upcoming sprint. We won't be able to release the changes until Crypto does their release, but in the meantime I have the following known tasks on my end:

• Update how we load the new "entrypoint loader" provided by build_web_compilers as it is throwing exceptions
• Add WASM tests to our continuous integration process

[asaarnak]

@tyllark The crypto: ^3.0.7 is also released now. Let me know if i can test it locally.

[tyllark]

Hello @asaarnak, thank you for the heads up! Ill ping you here once we have changes you can test locally.

[asaarnak]

Hei @tyllark, any updates on this?

[tyllark]

Hello @asaarnak, we do not have an update at this time. I'm working to get this prioritized given the amount of progress we've already made. I'll post here once we have an update.

[asaarnak]

@ekjotmultani @tyllark Hei! Any news on this issue?

[suryaishnavi]

@tyllarkHi, our team is eagerly awaiting the WASM update.
