ElevatedButton widget in Flutter 1000X600

How to use the ElevatedButton widget in Flutter?

This article will give examples of using the ElevatedButton widget in Flutter, starting with the most fundamental usage. It is the perfect example written by our Flutter experts, who have vast experience developing Flutter apps.

One of the buttons in Material Design in Flutter web is called Elevated Button has the feature of rising in elevation as the user presses it. Use the ElevatedButton widget in Flutter if you need to construct a Material Design elevated button.

When tapped by the user, these buttons’ primary feature is a small elevation of their surface toward the screen. Simply put, elevated buttons are raised, non-deprecated buttons without a clearly defined button style.

There are two parameters. It goes without saying that you must transmit a Widget as a child, usually a Text or an Icon widget. Additionally, you must pass the onPressed callback, which is triggered when a button is pressed by the user.

A static factory function ElevatedButton.icon makes it simpler for you to create an elevated button that has both Icon and Text widgets. For each icon and label, you must pass a Widget rather than a child.

This constructor can be used to create an ElevatedButton.

ElevatedButton(
{Key? key,
required VoidCallback? onPressed,
VoidCallback? onLongPress,
ValueChanged? onHover,
ValueChanged? onFocusChange,
ButtonStyle? style,
FocusNode? focusNode,
bool autofocus = false,
Clip clipBehavior = Clip.none,
MaterialStatesController? statesController,
required Widget? child}
)

What are the properties of an ElevatedButton?

1. autofocus:

It delivers a boolean value that corresponds to the button’s initial focus of Flutter.

2. clipBehaviour :

Whether or not the content is clipped is determined by clipBehavior.

3. focusNode:

Depicts the widget’s focus node.

4. ButtonStyle style:

Determines how the button will be styled

5. onLongPress :

When the button is long-pressed by the user, an action is to be taken called onLongPress.

6. enabled :

Gives a boolean value for the button’s activity called “enabled”

7. hashcode :

The button’s hashcode is determined by the hashcode.

8. onFocusChanged :

When a button’s focus changes, a method called onFocusChanged is called.

9. onHover :

The action that will be carried out when the user hovers over the button.
