How do I create an inline function to fix this error:
The argument type 'void Function()' can't be assigned to the parameter type 'void Function
.
Consider the following code:
Switch(value: _showChart, onChanged: () { //this generates the error
setState(() {
_showChart = value;
});
},)
If I extracted it to a function it would look something like this, but I don't want to do that:
VoidCallback? onSwitch(val){
setState(() {
_showChart = val;
});
}
Is there a way to do that inline?
CodePudding user response:
onChanged:
contains a value parameter.
You are missing a typo, the value
parameter. It will be,
Switch(
value: true,
onChanged: (value) {
setState(() {
_showChart = value;
});
},
),
