Code Review
This pull request adds several directional static members (topStart, topEnd, centerStart, centerEnd, bottomStart, bottomEnd) to the AlignmentGeometry class. This allows for more convenient use of AlignmentDirectional constants with dot shorthand syntax. The changes are well-tested. I've found a minor copy-paste error in the documentation for one of the new members, which I've commented on.

For a newbie, it might be unclear what "start" or "end" means. This was a little clearer before because AlignmentDirectional's docs hinted this was related to text direction.
I think we should add a hint to all these new directional members. For "start" side members, something like:
/// The top corner on the "start" side.
///
/// This can be used to indicate an offset from the left in [TextDirection.ltr]
/// text and an offset from the right in [TextDirection.rtl] text without having
/// to be aware of the current text direction.
///
/// See also:
///
/// * [AlignmentDirectional.topStart], which is the same thing.And for "end" side members, something like:
/// The top corner on the "end" side.
///
/// This can be used to indicate an offset from the right in [TextDirection.ltr]
/// text and an offset from the left in [TextDirection.rtl] text without having
/// to be aware of the current text direction.
///
/// See also:
///
/// * [AlignmentDirectional.topEnd], which is the same thing.

@ksokolovskyi Thanks for the wonderful contribution! I left a nitpick, but once that's addressed I think this is good to go! |

This pull request adds convenient static members for directional alignments (topStart, topEnd, etc.) to AlignmentGeometry, allowing for easier use with dot notation. The changes are well-implemented and include corresponding tests. My review includes one suggestion to use a documentation macro to reduce duplication in the comments for the new members, which will improve long-term maintainability.

To improve maintainability and reduce documentation duplication, consider using a {@macro} for the repeated explanation of directional alignment.
You could define a template, for example at the top of the file:
/// {@template flutter.painting.alignment.directional}
/// This can be used to indicate an offset from the left in [TextDirection.ltr]
/// text and an offset from the right in [TextDirection.rtl] text without having
/// to be aware of the current text direction.
/// {@endtemplate}And then use /// {@macro flutter.painting.alignment.directional} for this and the other 5 new static members. This would replace the paragraph explaining the behavior with LTR/RTL text directions.
/// {@macro flutter.painting.alignment.directional}

@ksokolovskyi This Gemini suggestion sounds good to me, but please use separate macros for start/end though.

@loic-sharma, thanks a lot for the review. What do you think about the latest Gemini suggestion? |

I thought this PR was related to #176507, but looks like that one is on a different class and done for a different reason. Just commenting so I don't lose them again. |
