Usage

To implement a snackbar, you can create SnackbarHost, which includes a LgnSnackbarHostState property. LgnSnackbarHostState provides access to the showSnackbar() function which you can use to display LgnSnackbar.

This suspending function requires a CoroutineScope such as with using rememberCoroutineScope — and can be called in response to UI events to show a LgnSnackBar within Scaffold.



Normal Snackbar

val scope =  rememberCourotineScope()
val snackbarHostState = remember { LgnSnackbarHostState() }
Scaffold(
  snackbarHost = {
    LgnSnackbarHost(
      hostState = snackbarHostState
      snackbar = {
        LgnSnackBar(it)
      }

Success Snackbar

  ...
  val snackbarHostState = remember { LgnSnackbarHostSate() }
  Scaffold(
  ...
  ){
    Button(
      onClick = {
        scope.launch{
          snackbarHostState.showSnackbarSuccess(...)

Info Snackbar

  ...
  val snackbarHostState = remember { LgnSnackbarHostSate() }
  Scaffold(
  ...
  ){
    Button(
      onClick = {
        scope.launch{
          snackbarHostState.showSnackbarInfo(...)

Error Snackbar

    ...
    val snackbarHostState = remember { LgnSnackbarHostSate() }
    Scaffold(
    ...
    ){
      Button(
        onClick = {
          scope.launch{
            snackbarHostState.showSnackbarError(...)

Warning Snackbar

   ...
   val snackbarHostState = remember { LgnSnackbarHostSate() }
   Scaffold(
   ...
   ){
     Button(
       onClick = {
         scope.launch{
           snackbarHostState.showSnackbarWarning(...)
