It works. It opens. It sets to true. But when you try to close you click outside the icon. So 2 events occur. You are closing it with handleClickOutside and then opening it again with handleCartActive. The right solution would be to use backdrop. When the dialog is open, show the backdrop and add event listener to it: when clicked outside the dialog, close it. And after closing it remove the event listener.

The quickest solution for you will be

<NavbarItem onClick={this.state.isCartActive ? undefined : ()=>{this.handleCartActive()}}>

Did you try with

this.setState({
  isCartActive: !isCartActive
})
