owner._debugCurrentBuildTarget == this , is not true

问题

[on web] tried to fit some widgets inside a FittedBox like this :

 FittedBox(
   fit: BoxFit.scaleDown,
   child: AnimatedContainer(...)
 )

but screen and console show only this message :

there's nothing else in the console

what's the next step here ? :D

回答1:

More Info was provided by the framework after a little messing around with the code , like extra children , random sizes to parents . . .

Error >> ... object was given an infinite size during layout

ultimately some like this worked :

FittedBox(
 fit: BoxFit.scaleDown,
 child: Container(
   height: MediaQuery.of(context).size.height * .65,
   child: AnimatedContainer(...)
)
