when will the Flutter-Quill SDK be adapted for the HarmonyOS system?

[wangjinshan]

Is there an existing issue for this?

• I have searched the existing issues

The question

"Hi, when will the Flutter-Quill SDK be adapted for the HarmonyOS system? I need to inform someone about the timeline for its release."

"We urgently need the Flutter-Quill SDK to be adapted for the HarmonyOS system."

Hope this helps!

There is no ETA, and we currently don't have a plan for it. Supporting desktop, mobile, and web platforms is already expensive as it's, I prefer to provide better support for current platforms and enhance functionality than adding support for a new platform.

The TargetPlatform is part of the Flutter SDK. This is a package target of the Flutter SDK. How can we support HarmonyOS? We can't change the target SDK to a modified version to support a new target platform. Providing another version of flutter_quill is also not something we plan on.

You can fork the project, adjust it, and use the fork as a git package in pubspec.yaml. Flutter Quill is a library.

Can you give me example packages that support it?

Subject: Assistance Required for Adapting Flutter Version for HarmonyOS

Dear quill

I hope this email finds you well.

We are currently working on adapting the Flutter version available at [https://gitee.com/harmonycommando_flutter/flutter] for HarmonyOS. However, we have encountered some issues with two specific files: delegate.dart and text_selection.dart.

We are unsure how to adapt these files for the HarmonyOS system. Below are the errors we are facing:

Could you please provide guidance or examples on how to properly adapt these files for HarmonyOS?

Thank you for your assistance.

• switch (defaultTargetPlatform)

I don't know anything about HarmonyOS though it probably has a similar behavior to Android, a workaround:

switch (defaultTargetPlatform) {
  case TargetPlatform.android:
  case TargetPlatform.ohos:
  // Assuming HarmonyOS has the same behavior as Android...
  break;
}

The project uses plugins and dependencies that don't support HarmonyOS yet, so it will probably have broken behavior and buggy.

We are currently working on adapting the Flutter version available at [https://gitee.com/harmonycommando_flutter/flutter] for HarmonyOS. However, we have encountered some issues with two specific files: delegate.dart and text_selection.dart.

This seems to be the same issue as #2389, closing as duplicate. Continue the discussion in there.
