Usage Guide

You can use Alwan composable as following:

Alwan(
  onColorChanged = { color -> },
  modifier = Modifier.width(300.dp),
)

onColorChanged is called whenever the user selects a new color.

Providing the default color:

Use AlwanState to control the initially selected color:

Alwan(
  onColorChanged = { },
  modifier = Modifier.width(300.dp),
  state = rememberAlwanState(initialColor = Color.Yellow),
)

Showing the alpha slider

The alpha slider is hidden by default. Use the showAlphaSlider parameter to show it:

Alwan(
  onColorChanged = { },
  showAlphaSlider = true,
)

Using AlwanDialog

You can use the AlwanDialog as following:

AlwanDialog(
  onColorChanged = { },
  onDismissRequest = { },
)

AlwanDialog can be customized with positive & negative buttons:

AlwanDialog(
  onDismissRequest = { },
  onColorChanged = { },
  positiveButtonText = "OK",
  onPositiveButtonClick = { },
  negativeButtonText = "CANCEL",
  onNegativeButtonClick = { },
)
