Simple Checkbox sample:

Parameters

checked

whether this checkbox is checked or unchecked

onCheckedChange

called when this checkbox is clicked. If null, then this checkbox will not be interactable, unless something else handles its input events and updates its state.

modifier

the Modifier to be applied to this checkbox

enabled

controls the enabled state of this checkbox. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.

colors

CheckboxColors that will be used to resolve the colors used for this checkbox in different states. See CheckboxDefaults.colors.

interactionSource

an optional hoisted MutableInteractionSource for observing and emitting Interactions for this checkbox. You can use this to change the checkbox's appearance or preview the checkbox in different states. Note that if null is provided, interactions will still happen internally.

This Checkbox function offers greater flexibility in visual customization. Using the Stroke parameters, you can control the appearance of both the checkmark and the box that surrounds it.

A sample of a Checkbox that uses a Stroke with rounded StrokeCap and androidx.compose.ui.graphics.StrokeJoin:

Parameters

checked

whether this checkbox is checked or unchecked

onCheckedChange

called when this checkbox is clicked. If null, then this checkbox will not be interactable, unless something else handles its input events and updates its state.

checkmarkStroke

stroke for the checkmark.

outlineStroke

stroke for the checkmark's box outline. Note that this stroke is applied when drawing the outline's rounded rectangle, so attributions such as androidx.compose.ui.graphics.StrokeJoin will be ignored.

modifier

the Modifier to be applied to this checkbox

enabled

controls the enabled state of this checkbox. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
