Thanks for the report. I see the same behavior and seems to be specific to desktop platform, as the same behavior occurs on macOS too, but works as expected on other platforms like mobile and web.

Verified on latest stable and master, running the code sample on Windows and macOS desktops, and we are unable to add space using spacebar while inputing text.

1. Windows Desktop:

2. macOS desktop:

3. Mobile and web:
   

flutter doctor -v

This is a regression caused by #80756 CC @dkwingsmt.

I could fix it by adding a DoNothingAndStopPropagationIntent for spaces on desktop, but that seems like a bandaid (here):

  SingleActivator(LogicalKeyboardKey.space): DoNothingAndStopPropagationTextIntent(),

Do we need to do some kind of check to only invoke the ActivateIntent if a field is not currently focused? Or any other way?

[dkwingsmt]

@justinmc Can you illustrate what of the change caused the regression?

[justinmc]

@dkwingsmt If I comment out this line and run it on a Mac then the bug is gone:

flutter/packages/flutter/lib/src/widgets/app.dart

Line 1213 in 0272047

SingleActivator(LogicalKeyboardKey.space): ActivateIntent(),

Maybe there's some small difference between LogicalKeySet and SingleActivator?

[justinmc]

Actually @LongCatIsLooong maybe your refactor #90684 will coincidentally fix this? Maybe then the Actions in the EditableText will receive the space before the ListTile does.

Actually @LongCatIsLooong maybe your refactor #90684 will coincidentally fix this? Maybe then the Actions in the EditableText will receive the space before the ListTile does.

If I'm understanding the issue correctly, that pull request does not change the current predefined shortcuts for text fields so it probably won't fix this issue.

I think this happens because TextFIeld doesn't override SingleActivator(LogicalKeyboardKey.space): ActivateIntent() and the ActivateIntent will end up being consumed by the ActivateIntent handler in the ink well. The enter key probably has this problem too.
We can override the shortcuts in EditableTextState but that will be the final override -- developers will lose the ability to further remap the space key to something else. We had a similar problem with Actions.

I just double checked my accusation of #80756 just to make sure, and I confirmed that the problem starts there, but I found that it's weirdly sporadic. When I checkout the merge commit b8833af, then the bug appears consistently like it does on master. When I checked out b8833af^ though, the bug can also still happen sometimes:

Screen.Recording.2021-10-01.at.3.58.18.PM.mov

[justinmc]

I opened a proposal PR to get the discussion going on one way of fixing this: #91129

Please read the code and description and let me know what you think! If we decide to go this way then I'll write tests and move it out of draft mode.
