I am trying to set the default value of the check box when the check box is unchecked
Initial state
this.state = {
checkbox: null,
}
<Checkbox
onChange={this.ChangeValue}
/>
ChangeValue= (event) => {
this.setState(
(prevState) => ({
checkbox: !prevState.checkbox,
})
})
When I click on the checkbox it sets to true which is fine when I unselect/uncheck the checkbox I need to set it to the default state value(null) instead of false
If you want the value to alternate between true and null that can be done like this:
this.setState(prevState => ({
checkbox: prevState.checkbox ? null : true
});
