In Android Compose, you can get the context by using the LocalContext, but it should be call'd from the composable function / scope.
val context = LocalContext.current
In the below code snippet we are retrieving the context and show a toast message inside the composable.
@Composable fun MyToastDisplay(name: String) { val ctx = LocalContext.current Column( Modifier .fillMaxHeight() .fillMaxWidth(), verticalArrangement = Arrangement.Center, horizontalAlignment = Alignment.CenterHorizontally ) { Text(text = "Hello $name", color = Color.Red, modifier = Modifier .background(Color.Green) .clickable { Toast .makeText(ctx, "Welcome to the Compose World", Toast.LENGTH_SHORT) .show() }) } }
If you use the LocalContext.current directly inside the clickable function results in the compilation error “@composable invocations can only happen from the context of an @composable function”.
Since the LocalContext.current is composable, you can’t invoke it within the non-composable function. i.e. clickable function is not a composable function and so can’t accept other composable functions.
Alternatively, you can get the context outside the clickable function scope and use, as shown in the above code snippet.
