e.stopPropagation() is different from e.preventDefault(), and your comment could be confused for the former.
You could phrase as follows: "Prevent the browser from inserting a new line when it's not a multiline input."

This looks great!
@mdebbar would it be worth adding a test to verify return key behavior for multiline inputs is preserved?

There is already a test for that right above this :)

@htoor3 If I remember well this is already covered by an existing test. (I first I implemented this change for both single line and multiline inputs and it broke several tests. I ended targeting only single line, not because of those failing tests, but because changing the behavior for multilines inputs will require some discussions. I will open a new issue to discuss this, see flutter/flutter#113559 (comment)).

#53453) ## Description This PR prevents new line key event from being dispatched for a multiline text field when `TextField.textInputAction` is not `TextInputAction.newline`. Since #33428, web engine does not prevent new line key events. In #36893, I fixed a similar issue for single line text fields. At that time I was not sure if we want to fix it for multiline text fields. I checked again on non-web platforms (macos, iOS, Android) and the new line is not added if the input action is not `TextInputAction.newline`. For a **multiline field**, the default text input action is `TextInputAction.newline`. If the developer sets text input action to another value: - before this PR, the action is performed and a new line is added. - after this PR, the action is performed but no new line is added. ## Related Issue Fixes flutter/flutter#145051 ## Tests Adds 1 tests, updates 3 tests.

Description
This PR prevents new line key event from being dispatched when
TextField.textInputActionis notTextInputAction.newlineand the text field is not multiline.Related Issue
Fixes flutter/flutter#113559
Implementation choice
Since #33428, web engine does not prevent new line key events.
Here, I choose to prevent it whether the field is multiline or not.For a single line field (the default text input action is
TextInputAction.done):TextInputAction.nextfor instance), the newly focused field inserts the new line (see [Web] TextField receiving newline on TextInputAction.next flutter#113559).For a multiline field, the default text input action is
TextInputAction.newline.If the developer sets text input action to another value:
after this PR, the action is performed but no new line is added.@mdebbar For multiline text fields, it seems that it was expected to always insert a new line.
I think that it should not when the user choose to set the input action to something else than.TextInputAction.newlineEdit: I have tested on Linux and MacOS and on both platforms a new line is inserted and the action is performed. So it is probably better to do the same on Web for the moment.
