_RenderWeekIndicatorText does not meet its constraints

[abel-123]

Using alpha 10 version, loading the timetable widget throws an exception:

======== Exception caught by rendering library =====================================================
The following assertion was thrown during performLayout():
_RenderWeekIndicatorText does not meet its constraints.

Constraints: BoxConstraints(0.0<=w<=14.0, 0.0<=h<=309.5)
Size: Size(16.0, 16.0)

If you are not writing your own RenderBox subclass, then this is not your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=2_bug.md

The relevant error-causing widget was:
MultiDateTimetable MultiDateTimetable:file:///C:/Users/healt/AndroidStudioProjects/MyWod/lib/screens/timetable/timetable.dart:67:24

My code:

This is fixed as part of v1.0.0-alpha.11
