The user can select one or multiple at a time depending on the situation. The checkbox is a binary value with yes and no. The value is checked if it is yes and unchecked if it is no. Let us now see the different types of GFCheckBox in the below section
Flutter Basic Checkbox
This is a basic or standard type of checkbox. It has a slight border radius around it. By using the below code we can design a basic Checkbox.bool isChecked = false;
GFCard(
content: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
GFCheckbox(
activeBgColor: Colors.red,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
activeBgColor: Colors.blue,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
size: GFSize.SMALL,
activeBgColor: Colors.green,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
],
),
),Flutter Square Checkbox
This is a square type of checkbox. It doesn't have any border radius. We use GFCheckboxType.square to make it of type square. Use the below code to make a square Checkbox.bool isChecked = true;
GFCard(
content: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
GFCheckbox(
size: GFSize.LARGE,
activeBgColor: Colors.red,
type: GFCheckboxType.square,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
type: GFCheckboxType.square,
activeBgColor: Colors.blue,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
size: GFSize.SMALL,
activeBgColor: Colors.green,
type: GFCheckboxType.square,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
],
),
),Flutter Circular Checkbox
This is a circular type checkbox. The shape is of a circle or round as shown in the below image. Add type GFCheckboxType.circle to make it a circle. Use the below example to show the Flutter circular Checkbox.bool isChecked = false;
GFCard(
content: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
GFCheckbox(
size: GFSize.LARGE,
activeBgColor: Colors.red,
type: GFCheckboxType.circle,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
type: GFCheckboxType.circle,
activeBgColor: Colors.blue,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
),
GFCheckbox(
activeBgColor: Colors.green,
size: GFSize.MEDIUM,
type: GFCheckboxType.circle,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
],
),
),Flutter Custom Checkbox Widget With Icon
The Custom CheckBox can have an icon or background image as the check value shown in the image below. We can customize the widget by using its property. Use the below example to make a custom Checkbox.bool isChecked = true;
GFCard(
content: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
GFCheckbox(
size: GFSize.LARGE,
type: GFCheckboxType.custom,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: null,
),
GFCheckbox(
type: GFCheckboxType.square,
activeBgColor: Colors.purple,
activeIcon: Icon(Icons.sentiment_satisfied),
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
inactiveIcon: Icon(Icons.sentiment_dissatisfied),
),
GFCheckbox(
size: GFSize.SMALL,
type: GFCheckboxType.custom,
onChanged: (value) {
setState(() {
isChecked = value;
});
},
value: isChecked,
custombgColor: Colors.blue,
),
],
),
