Steps to Reproduce
enum Phone {
samsung,
google,
}
Phone phone = Phone.samsung;
void method() {
switch(phone) {
}
}
When you hover over to the switch(phone), it will tell you to implement all the cases for Phone enum, now there should be a way/shortcut that will let IDE to create all the cases in 1 click.
