It is important to note that when you create a form you should provide a Global key. flutter form can contain text fields, buttons, radio buttons, check boxes, etc Here we group and validate multiple form fields. There is a form widget in flutter which provides all the facilities a form needs. It also provides a simple way to use regex for validation very easily. You need to type only a few lines of code. The validator package makes things very simple. In our example app, we use the validator package along with regex. One way to do it is by using the validator package and the other way is by using Regular Expressions (Regex). In flutter, you can do validation in two ways. We will force the user to enter only a valid name, a valid email, and a valid phone number. For example, if we want to collect some data about a person, let’s say his name, email, and phone number.
Validations are actually the constraints or restrictions on the data to be collected from the user. The data may be used for searching, saving user info, filtering, logging in, or something else.
For example, the user’s name, email, address, phone number, date of birth, etc. A form is an easy way to collect some specific data from users. What is form?Ī form is a window or a screen that contains fields or some space to enter data.
