ElevatedButton class

A Material Design "elevated button".

Use elevated buttons to add dimension to otherwise mostly flat layouts, e.g. in long busy lists of content, or in wide spaces. Avoid using elevated buttons on already-elevated content such as dialogs or cards.

An elevated button is a label child displayed on a Material widget whose Material.elevation increases when the button is pressed. The label's Text and Icon widgets are displayed in style's ButtonStyle.foregroundColor and the button's filled background is the ButtonStyle.backgroundColor.

The elevated button's default style is defined by defaultStyleOf. The style of this elevated button can be overridden with its style parameter. The style of all elevated buttons in a subtree can be overridden with the ElevatedButtonTheme, and the style of all of the elevated buttons in an app can be overridden with the Theme's ThemeData.elevatedButtonTheme property.

The static styleFrom method is a convenient way to create a elevated button ButtonStyle from simple values.

If onPressed and onLongPress callbacks are null, then the button will be disabled.

This sample produces an enabled and a disabled ElevatedButton.

To create a local project with this code sample, run:
flutter create --sample=material.ElevatedButton.1 mysample

Typically the button's label.
clipBehavior Clip?
The content will be clipped (or not) according to this option.
enabled bool
Whether the button is enabled or disabled.
no setterinherited
focusNode FocusNode?
An optional focus node to use as the focus node for this widget.
hashCode int
The hash code for this object.
no setterinherited
iconAlignment IconAlignment
Determines the alignment of the icon within the widgets such as:
isSemanticButton bool?
Determine whether this subtree represents a button.
key Key?
Controls how one widget replaces another widget in the tree.
onFocusChange ValueChanged<bool>?
Handler called when the focus changes.
onHover ValueChanged<bool>?
Called when a pointer enters or exits the button response area.
onLongPress VoidCallback?
Called when the button is long-pressed.
onPressed VoidCallback?
Called when the button is tapped or otherwise activated.
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
statesController MaterialStatesController?
Represents the interactive "state" of this widget in terms of a set of MaterialStates, like MaterialState.pressed and MaterialState.focused.
style ButtonStyle?

Defines the button's default appearance.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
themeStyleOf(BuildContext context) ButtonStyle?
Returns the ElevatedButtonThemeData.style of the closest ElevatedButtonTheme ancestor.
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) String
A string representation of this object.
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) String
Returns a string representation of this node and its descendants.
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) String
