Form

You must have seen the login or signup form where we have to fill in our name/username, email, and password from our keyboard, and the UI shows whatever you enter in their respective fields but not in the password that is obscured from us. Also, if a field doesn’t fulfill the validation, the respective field will throw an error with an appropriate message, like password is too short.

All these features can be implemented in Flutter with the help of the Form widget. So let’s build our own sign-up page.
