OudsCheckbox class
OUDS Checkbox design guidelines
Checkboxes are input controls that allow users to select one or more options from a number of choices.
This checkbox supports the indeterminate state: Checkboxes can have a parent-child relationship with other checkboxes. When the parent checkbox is checked, all child checkboxes are checked. If a parent checkbox is unchecked, all child checkboxes are unchecked. If some, but not all, child checkboxes are checked, the parent checkbox becomes an indeterminate checkbox.
The following parameters are available:
- value: Controls checked state of the checkbox.
- onChanged: Callback invoked on checkbox click. If
null
, then this is passive and relies entirely on a higher-level component to control the checked state. - tristate: If true, the checkboxes value can be true, false, or null. If false, only true and false states are managed.
- isError: Controls the error state of the checkbox.
You can use OudsCheckbox like this :
Enabled checkbox sample :
The status of the checkbox before a user has interacted with it, or other content affects it.
OudsCheckbox(
value: isChecked,
onChanged: (bool? newValue) {
setState(() {
isCheckedFirst = newValue;
});
},
isError: false,
);
