ToggleButton

Component in Material 3 Compose

TODO link to mio page when available.

Toggle button is a toggleable button that switches between primary and tonal colors depending on [checked]'s value. It also morphs between the three shapes provided in [shapes] depending on the state of the interaction with the toggle button as long as the three shapes provided our [CornerBasedShape]s. If a shape in [shapes] isn't a [CornerBasedShape], then toggle button will toggle between the [ButtonShapes] according to user interaction.

TODO link to an image when available

see [Button] for a static button that doesn't need to be toggled. see [IconToggleButton] for a toggleable button where the content is specifically an [Icon].

Parameters

name	description
checked	whether the toggle button is toggled on or off.
onCheckedChange	called when the toggle button is clicked.
modifier	the [Modifier] to be applied to the toggle button.
enabled	controls the enabled state of this toggle button. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
shapes	the [ButtonShapes] that the toggle button will morph between depending on the user's interaction with the toggle button.
colors	[ToggleButtonColors] that will be used to resolve the colors used for this toggle button in different states. See [ToggleButtonDefaults.toggleButtonColors].
elevation	[ButtonElevation] used to resolve the elevation for this button in different states. This controls the size of the shadow below the button. See [ButtonElevation.shadowElevation]. Additionally, when the container color is [ColorScheme.surface], this controls the amount of primary color applied as an overlay.
border	the border to draw around the container of this toggle button.
contentPadding	the spacing values to apply internally between the container and the content
interactionSource	an optional hoisted [MutableInteractionSource] for observing and emitting [Interaction]s for this toggle button. You can use this to change the toggle button's appearance or preview the toggle button in different states. Note that if null is provided, interactions will still happen internally.
content	The content displayed on the toggle button, expected to be text, icon or image.
