so this is necessary because using const Locale('fa', 'IR'), //'H:mm' but RTL, the x button will go to the other side which causes the hit testing to not hit test on the specified widget in the next iterations, and the following warning will appear:

Warning: A call to tap() with finder "Found 1 widget with text "X": [
  Text("X", dependencies: [DefaultSelectionStyle, DefaultTextStyle, MediaQuery]),
]" derived an Offset (Offset(400.0, 300.0)) that would not hit test on the specified widget.
Maybe the widget is actually off-screen, or another widget is obscuring it, or the widget cannot receive pointer events.
The finder corresponds to this RenderBox: RenderParagraph#4315d relayoutBoundary=up13
The hit test result at that offset is: HitTestResult(RenderPointerListener#53575@Offset(124.0, 108.0), RenderSemanticsGestureHandler#e488f@Offset(124.0, 108.0), RenderPointerListener#10b37@Offset(124.0, 108.0), _RenderScrollSemantics#5bd15@Offset(124.0, 108.0), RenderClipRect#b4b84@Offset(124.0, 108.0), _RenderSingleChildViewport#1766f@Offset(124.0, 108.0), RenderIgnorePointer#c357a@Offset(124.0, 108.0), RenderSemanticsAnnotations#c6d85@Offset(124.0, 108.0), RenderPointerListener#f33fd@Offset(124.0, 108.0), RenderSemanticsGestureHandler#d85b7@Offset(124.0, 108.0), RenderPointerListener#8d4cb@Offset(124.0, 108.0), _RenderScrollSemantics#65c57@Offset(124.0, 108.0), RenderClipRect#c7224@Offset(124.0, 108.0), _RenderLayoutBuilder#e9b18@Offset(124.0, 108.0), RenderPadding#0920f@Offset(148.0, 132.0), _RenderInkFeatures#8ee06@Offset(148.0, 132.0), RenderCustomPaint#ec0c5@Offset(148.0, 132.0), RenderPhysicalShape#68177@Offset(148.0, 132.0), RenderConstrainedBox#a622e@Offset(148.0, 132.0), RenderPositionedBox#f0706@Offset(384.0, 300.0), RenderPadding#1abd3@Offset(400.0, 300.0), RenderSemanticsAnnotations#e5163@Offset(400.0, 300.0), RenderPadding#526c7@Offset(400.0, 300.0), RenderSemanticsAnnotations#29bdc@Offset(400.0, 300.0), RenderPadding#3d688@Offset(400.0, 300.0), RenderSemanticsAnnotations#b694c@Offset(400.0, 300.0), RenderRepaintBoundary#880f7@Offset(400.0, 300.0), RenderIgnorePointer#e2358@Offset(400.0, 300.0), RenderAnimatedOpacity#a7c38@Offset(400.0, 300.0), RenderRepaintBoundary#3935d@Offset(400.0, 300.0), RenderSemanticsAnnotations#516f0@Offset(400.0, 300.0), RenderOffstage#b471e@Offset(400.0, 300.0), RenderSemanticsAnnotations#f5af2@Offset(400.0, 300.0), _RenderTheater#4bd23@Offset(400.0, 300.0), RenderAbsorbPointer#4c1cf@Offset(400.0, 300.0), RenderPointerListener#1cee2@Offset(400.0, 300.0), RenderSemanticsAnnotations#2e617@Offset(400.0, 300.0), RenderCustomPaint#f4bcb@Offset(400.0, 300.0), RenderSemanticsAnnotations#60900@Offset(400.0, 300.0), RenderSemanticsAnnotations#d4d73@Offset(400.0, 300.0), RenderSemanticsAnnotations#d4f6b@Offset(400.0, 300.0), RenderTapRegionSurface#2ba9e@Offset(400.0, 300.0), RenderSemanticsAnnotations#3169a@Offset(400.0, 300.0), RenderSemanticsAnnotations#2c6d3@Offset(400.0, 300.0), HitTestEntry<HitTestTarget>#4b488(_ReusableRenderView#5b5d7), HitTestEntry<HitTestTarget>#ca173(<AutomatedTestWidgetsFlutterBinding>))

it is also possible to repro the bug with moving const Locale('fa', 'IR'), //'H:mm' but RTL as the first locale to see the same warning, not sure if this is a known bug or the expected behavior.
