}

Quick start

In order to start using the library you need to wrap your composables in a TapTargetCoordinator

TapTargetCoordinator(showTapTargets = true, onComplete = {}) {
  Surface {
    Button(
      onClick = { },
      modifier = Modifier.tapTarget(
        precedence = 0,
        title = TextDefinition(
          text = "Tap target title",
          textStyle = MaterialTheme.typography.titleLarge,
          fontWeight = FontWeight.Bold,
          color = MaterialTheme.colorScheme.onSecondaryContainer
        ),
        description = TextDefinition(
          text = "Tap target description",
          textStyle = MaterialTheme.typography.bodyMedium,
          color = MaterialTheme.colorScheme.onSecondaryContainer
        ),
        tapTargetStyle = TapTargetStyle(
          backgroundColor = MaterialTheme.colorScheme.secondaryContainer,
          tapTargetHighlightColor = MaterialTheme.colorScheme.onSecondaryContainer,
          backgroundAlpha = 1f,
        ),
      ),
    ) {
      Text(text = "Click here")
    }
  }
}

You can also create a TapTargetDefinition and pass it to the modifier:

val tapTargetDefinition = TapTargetDefinition(
  precedence = 1,
  title = TextDefinition(
    text = "Tap target title",
    textStyle = MaterialTheme.typography.titleLarge,
    fontWeight = FontWeight.Bold,
    color = MaterialTheme.colorScheme.onSecondaryContainer
  ),
  description = TextDefinition(
    text = "Tap target description",
    textStyle = MaterialTheme.typography.bodyMedium,
    color = MaterialTheme.colorScheme.onSecondaryContainer
  ),
  tapTargetStyle = TapTargetStyle(
    backgroundColor = MaterialTheme.colorScheme.secondaryContainer,
    tapTargetHighlightColor = MaterialTheme.colorScheme.onSecondaryContainer,
    backgroundAlpha = 1f,
  ),
)

TapTargetCoordinator(showTapTargets = true, onComplete = {}) {
  Surface {
    Button(
      onClick = {  },
      modifier = Modifier.tapTarget(tapTargetDefinition),
    ) {
      Text(text = "Click here")
    }
  }
}

The library supports chaining of multiple tap targets, but you can also show only one if that's what you need.
