Methods
alert
Launches an alert dialog with the specified title and optional message.
Optionally, an array of buttons can be provided: on Android the maximum is 3,
on iOS any number is okay.
On Android, the dialog can be dismissed by tapping outside of the alert box.
This triggers the onDismiss callback available in the options. With the
cancelable option, this behavior can be deactivated altogether.
alert: (
~title: string,
~message: string=?,
~buttons: array<button>=?,
~options: options=?,
) => unit
