Whole Exception log
════════ Exception caught by rendering library ═════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
BoxConstraints forces an infinite height.
These invalid constraints were provided to RenderFlex's layout() function by the following function, which probably computed the invalid constraints in question:
RenderStack.performLayout (package:flutter/src/rendering/stack.dart:510:15)
The offending constraints were: BoxConstraints(w=392.7, h=Infinity)
User-created ancestor of the error-causing widget was:
SingleChildScrollView file:///home/ctpl119/Documents/NEW_PROJECT/oricon/oricon/lib/register.dart:23:15
When the exception was thrown, this was the stack:
#0 BoxConstraints.debugAssertIsValid.<anonymous closure>.throwError (package:flutter/src/rendering/box.dart:501:9)
#1 BoxConstraints.debugAssertIsValid.<anonymous closure> (package:flutter/src/rendering/box.dart:548:21)
#2 BoxConstraints.debugAssertIsValid (package:flutter/src/rendering/box.dart:552:6)
#3 RenderObject.layout (package:flutter/src/rendering/object.dart:1618:24)
