I'm following a 2019 flutter course ( the teacher explains every concept with clear explanations and tangible examples) but due to the difference in flutter versions and me being completely new to mobile app development, I get errors all the time.
This time I couldn't find an answer that could help me so I decided to ask here myself for the first time.
This is the full error I get
======== Exception caught by widgets library =======================================================
The following assertion was thrown building RoundIconButton(dirty):
setState() or markNeedsBuild() called during build.
This InputPage widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase.
The widget on which setState() or markNeedsBuild() was called was: InputPage
dependencies: [_InheritedTheme, _LocalizationsScope-[GlobalKey#9665e]]
state: _InputPageState#b079c
The widget which was currently being built when the offending call was made was: RoundIconButton
dirty
The relevant error-causing widget was:
RoundIconButton RoundIconButton:file:///C:/Users/murod/StudioProjects/bmi_calculator/lib/input_page.dart:144:29
When the exception was thrown, this was the stack:

====================================================================================================
======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 199834 pixels on the right.
The relevant error-causing widget was:
Row Row:file:///C:/Users/murod/StudioProjects/bmi_calculator/lib/input_page.dart:130:25
The overflowing RenderFlex has an orientation of Axis.horizontal.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.
The specific RenderFlex in question is: RenderFlex#80ab8 relayoutBoundary=up6 OVERFLOWING

======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 99932 pixels on the bottom.
The relevant error-causing widget was:
Column Column:file:///C:/Users/murod/StudioProjects/bmi_calculator/lib/input_page.dart:121:32
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.
The specific RenderFlex in question is: RenderFlex#5a9a0 relayoutBoundary=up5 OVERFLOWING
... parentData: <none> (can use size)
... constraints: BoxConstraints(w=175.7, 0.0<=h<=147.8)
... size: Size(175.7, 147.8)
... direction: vertical
... mainAxisAlignment: center
... mainAxisSize: min
... crossAxisAlignment: center
... verticalDirection: down

====================================================================================================
This is the code that the error says it originated from ( everything started when I added the onPressed. Before that, there were no errors)
Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text('WEIGHT', style: kLabelTextStyle),
Text(
weight.toString(),
style: kNumberTextStyle,
),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
RoundIconButton(
icon: FontAwesomeIcons.minus,
onPressed: () {
setState(() {
weight--;
});
},
),
const SizedBox(
width: 10,
),
RoundIconButton(
icon: FontAwesomeIcons.plus,
onPressed: () {
setState(() {
weight ;
});
},
),
],
)
],
)
Here is the RoundIconButton code:
class RoundIconButton extends StatelessWidget {
RoundIconButton({required this.icon, required this.onPressed});
final IconData icon;
final Function onPressed;
@override
Widget build(BuildContext context) {
return RawMaterialButton(
child: Icon(icon),
constraints: const BoxConstraints.tightFor(width: 55, height: 55),
shape: const CircleBorder(),
fillColor: const Color(0xFF4C4F5E),
onPressed: onPressed(),
);
}
}
Thank you for your help
CodePudding user response：
Apparently you have typed some extra characters, Try this instead.
onPressed: () {
setState(){ weight ; };
},
CodePudding user response：
I used "➡" and "⬅" to indicate where the changes were made in the code
The solution was simply changing
class RoundIconButton extends StatelessWidget {
RoundIconButton({required this.icon, required this.onPressed});
final IconData icon;
➡ final Function onPressed; ⬅
@override
Widget build(BuildContext context) {
return RawMaterialButton(
child: Icon(icon),
constraints: const BoxConstraints.tightFor(width: 55, height: 55),
shape: const CircleBorder(),
fillColor: const Color(0xFF4C4F5E),
➡ onPressed: onPressed(), ⬅
);
}
}
to
class RoundIconButton extends StatelessWidget {
RoundIconButton({required this.icon, required this.onPressed});
final IconData icon;
➡ final Function() onPressed; ⬅
@override
Widget build(BuildContext context) {
return RawMaterialButton(
child: Icon(icon),
constraints: const BoxConstraints.tightFor(width: 55, height: 55),
shape: const CircleBorder(),
fillColor: const Color(0xFF4C4F5E),
➡ onPressed: onPressed, ⬅
);
}
}
The change was adding to "final Function () onPressed;"
and removing the parenthesis in "onPressed: onPressed,"
