OverflowIndicator alignment on the right / bottom #6

Closed caduandrade closed 3 years ago

The OverflowIndicator is positioned next to the children but could be aligned as well on the opposite side, filling the remaining space. Screenshot_20210313_195938

If I understood, I think the solution is pretty simple. Could define some bool to configure it. The default value could be false to keep current behavior. Then the change should only add this line:

if (_isAnchored) { offset += availableExtent - childMainSize; }

before line 290 (src/rendering/overflow_view.dart):

overflowIndicatorParentData.offset = _isHorizontal ? Offset(offset, 0) : Offset(0, offset);

Of course, after NullSafety merge, this line number will change ;-) I can try a PR after the NullSafety if you want.

"_isAnchored" is just a suggestion.

Tks!
