Initialization

To initialize the SDK you have to add MBMessages to the array of plugins of MBurger.

MBManager.shared.apiToken = 'YOUR_API_TOKEN';
MBManager.shared.plugins = [MBMessages()];

To show in app message correctly you have to embed your main widget in a MBMessagesBuilder like this:

Widget build(BuildContext context) {
return MaterialApp(
...
home: MBMessagesBuilder(
child: Scaffold(
...
),
),
);
}

Why? To present in app messages MBMessages uses the showDialog function that needs a BuildContext. Embedding your main Scaffold in a MBMessagesBuilder let the SDK know always what context to use to show in app messages.

Initialize MBMessages with parameters

You can set a couples of parameters when initializing the MBMessages plugin:

MBMessages messagesPlugin = MBMessages(
messagesDelay: 1,
automaticallyCheckMessagesAtStartup: true,
debug: false,
themeForMessage: (message) => MBInAppMessageTheme(),
onButtonPressed: (button) => _buttonPressed(button),
);
  • messagesDelay: it's the time after which the messages will be displayed once fetched

  • automaticallyCheckMessagesAtStartup: if the plugin should automatically check messages at startup. By default it's true.

  • debug: if this is set to true, all the message returned by the server will be displayed, if this is set to false a message will appear only once for app installation. This is false by default

  • themeForMessage: a function to provide a message theme (colors and fonts) for in app messages.

  • onButtonPressed: a callback called when a button of an in app message iis pressed.
