Modifier 开关(Toggleable)

toggleable 修饰符非常适合用来做开关效果

triStateToggleable 修饰符为三态开关（启用、停用和不确定）

fun Modifier.toggleable(
    value: Boolean,
    enabled: Boolean,
    role: Role?,
    onValueChange: (Boolean) -> Unit
)

fun Modifier.toggleable(
    value: Boolean,
    interactionSource: MutableInteractionSource,
    indication: Indication?,
    enabled: Boolean,
    role: Role?,
    onValueChange: (Boolean) -> Unit
)

fun Modifier.triStateToggleable(
    state: ToggleableState,
    enabled: Boolean,
    role: Role?,
    onClick: () -> Unit
)

fun Modifier.triStateToggleable(
    state: ToggleableState,
    interactionSource: MutableInteractionSource,
    indication: Indication?,
    enabled: Boolean,
    role: Role?,
    onClick: () -> Unit
)

• value: Toggleable 是打开还是关闭
• enabled: 启用Toggleable
• interactionSource: 按下时发出此状态
• indication: 按下修改后的元素时显示的指示。默认情况下，LocalIndication将使用指示。传递null以显示无指示，
• role: 用户界面元素的类型。
• onValueChange: 单击 toggleable 时调用的回调
• onClick: 在用户单击可切换时调用

@Composable
fun ToggleableDemo() {
    var checked by remember { mutableStateOf(false) }
    // content that you want to make toggleable
    Text(
        modifier = Modifier.toggleable(value = checked, onValueChange = { checked = it }),
        text = checked.toString()
    )
}

@Composable
fun TriStateToggleableDemo() {
    var checked by remember { mutableStateOf(ToggleableState.Indeterminate) }
    // content that you want to make toggleable
    Text(
        modifier = Modifier.triStateToggleable(
            state = checked,
            onClick = {
                checked =
                    if (checked == ToggleableState.On)
                        ToggleableState.Off
                    else
                        ToggleableState.On
            }
        ),
        text = checked.toString()
    )
}
