Animate change on height when child of container renders. In the end I just had to use AnimatedSize. It replicates exactly the animation that I want.
1 2 3 4 5 6 7 8 9 10 11 12 | AnimatedSize( vsync: this, duration: Duration(milliseconds: 150), curve: Curves.fastOutSlowIn, child: Container( child: Container( child: !_isExpanded ? null : FadeTransition(opacity: animationFade, child: widget.child), ), ), ); |
