+1 facing the same problem

Any update on this ? It's been about 1 year

@Andre-lbc does this issue still persists?

does this issue still persists?

#1937 Fixed a similar issue on macOS. I remember it was an issue on Linux too.

Sorry, I just saw this, I'll check it out and get back to you tomorrow.

Hi, I can confirm that I can still reproduce these errors with the latest stable version available to me (flutter_quill: 10.7.5)

Console logs:

Thank you for the input, I was indicating that there was a similar issue (unimplemented intent action) that's also on macOS that's fixed, will fix this issue in a similar way as soon as we can.

The following intents are both missing and need actions that implement them:

• ExpandSelectionToDocumentBoundaryIntent: Expands the current selection to the document boundary in the direction given by the forward property.
• ExpandSelectionToLineBreakIntent: Expands the current selection to the closest line break in the direction
  given by the forward property.

This is similar to #1937.

It seems that ExtendSelectionToNextParagraphBoundaryOrCaretLocationIntent is also not implemented:

The following assertion was thrown during method call TextInputClient.performSelectors:
Unable to find an action for an Intent with type ExtendSelectionToNextParagraphBoundaryOrCaretLocationIntent in an Actions widget in the given context.

Unable to find an action for an Intent with type ExtendSelectionToNextParagraphBoundaryOrCaretLocationIntent in an Actions widget in the given context.

Fixed in #2279.

Will need more time to complete the bug fix, also notice some other related bugs, undocumented actions/intents, inconsistency with the naming, missing tests, some other intents to be implemented, code duplication to achieve a task, and common functionalities being duplicated all over the source code.

Which is why more time needed before releasing an incomplete bug fix.

For now, you can test and see if the issue exist on the branch of #2279:

$ git clone --depth 1 --branch fix/1192 https://github.com/singerdmx/flutter-quill.git
$ (cd example/macos && pod update OrderedSet && pod install --repo-update)
$ (cd example && flutter run -d macos)

It looks like the new version of flutter_inappwebview is causing build issues on macOS as well:

@Andre-lbc Can you confirm if this issue is fixed with 10.8.5?

Hello @EchoEllet,
Thanks!

Just upgraded to 10.8.5 and ran it on macOS:

command + shift + arrow up and command + shift + arrow down no longer throw exceptions and are showing the expected behavior.

command + shift + arrow left and command + shift + arrow right no longer throw exceptions, but are showing slightly different behavior than their native counterpart: they now expand the selection to the end/beginning of the paragraph, whereas on native they expand until the end/beginning of the line.

no longer throw exceptions, but are showing slightly different behavior than their native counterpart: they now expand the selection to the end/beginning of the paragraph, whereas on native they expand until the end/beginning of the line.

I'm unsure about the expected native behavior on macOS though the current behavior does what you described, see ExpandSelectionToLineBreakAction.

Can you share an example video of a macOS app that implements this shortcut as expected?

Of course, here are some examples:

I think this is not dependent on the application level implementation, as all third-party apps I have used so far support this (Firefox, Chrome, Visual Studio Code, Notion, Word, Excel, OneNote, Android Studio, etc)
