======== Exception caught by widgets library =======================================================
The following assertion was thrown building AnimatedContainer-[<Instance of 'Tab'>](duration: 167ms, BoxConstraints(w=240.0, 0.0<=h<=Infinity), clipBehavior: Clip.none, dirty, state: _AnimatedContainerState#eb24a(ticker active, BoxConstraintsTween(BoxConstraints(unconstrained) → BoxConstraints(w=240.0, 0.0<=h<=Infinity)))):
Cannot interpolate between finite constraints and unbounded constraints.
'package:flutter/src/rendering/box.dart':
Failed assertion: line 479 pos 12: '(a.maxWidth.isFinite && b.maxWidth.isFinite) || (a.maxWidth == double.infinity && b.maxWidth == double.infinity)'
Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
