I would like to have an input that updates continuously as the user types and then loses focus. The feedback will be a border around the input.
1 Green: when valid2 Amber: when typing and is in error state (Green when valid)3 Red: when in error state and unfocused4 Nothing: when input is pristine (not touched and empty)What is the best way to achieve this?
Ideally this will work with both iOS and Android.
