Flutter Handling Null Value in TextField
I am writing this post for my self reference. I got serious issues when I parse a TextField value to a double or any other data type. This will throw exception when you clear the TextField. So I add if condition like this. Again, this throws error while clearing the TextField. To avoid this issue, we can add a TextEditingController for the TextField and check whether the field is empty. Happy Coding!
