Today we will see how to use form and textfields.
One of the key components in Flutter is the form and TextFormField, which can be used to build user input forms in your app.
To use form and TextFormField in Flutter, you need to import the form package and wrap your form widgets in a Form widget. Inside the Form widget, you can use the TextFormField widget to create input fields for user input.
To create a form with a single text input field, we can use the following code:
In the code above, we create a Form widget with a TextFormField and a RaisedButton. The TextFormField has a decoration property to customize the appearance of the input field, and a validator function to check the user input. The onSaved function is called when the form is submitted, and it saves the user input to a variable.
The RaisedButton has an onPressed function that calls the validate and save methods on the FormState object to validate and save the user input. If the form is valid, it shows a snackbar with the user input.
We can add more input fields to the form by adding more TextFormField widgets inside the Column widget. You can also customize the appearance of the form and the input fields using the various properties and styles available in Flutter.
In short using form and TextFormField in Flutter is a simple and powerful way to build user input forms in your app. With a few lines of code, you can create a form with multiple input fields and validate and save the user input.
