Flutter Presentation Display is a Flutter plugin designed to run on multiple displays, including handling secondary (presentation) display. It provides methods to interact with connected displays, transfer data, and respond to display connection changes. Tested on SUNMI T2s.

• Retrieve a list of connected displays
• Show and hide secondary (presentation) display
• Transfer data from the main display to the secondary display or vice versa
• Listen to display connection changes

Add flutter_presentation_display to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  flutter_presentation_display: any  # Replace with the latest version

import 'package:flutter_presentation_display/flutter_presentation_display.dart';

Initialize FlutterPresentationDisplay

Create an instance of FlutterPresentationDisplay:

final display = FlutterPresentationDisplay();

Retrieve Displays

Get a list of connected displays:

List<Display>? displays = await display.getDisplays();

Get Display Name by ID Retrieve the name of a display using its ID:

String? displayName = await display.getNameByDisplayId(1);

Get Display Name by Index Retrieve the name of a display using its index in the list:

String? displayName = await display.getNameByIndex(0);

Show and Hide Secondary Display

Show a secondary display with a specific ID and router name:

bool? result = await display.showSecondaryDisplay(
  displayId: 1,
  routerName: "presentation",
);

Hide a secondary display using its ID:

bool? result = await display.hideSecondaryDisplay(displayId: 1);

Transfer Data to and from Displays

Transfer data to the secondary (presentation) display:

bool? result = await display.transferDataToPresentation({"key": "value"});

Transfer data to the main display:

bool? result = await display.transferDataToMain({"key": "value"});

Listen to Display Connection Changes

Listen to changes in connected displays:

display.connectedDisplaysChangedStream.listen((int? displayId) {
  print('Connected display ID: $displayId');
});

Listen for Data from Displays

Listen for data sent from the secondary (presentation) display:

display.listenDataFromPresentationDisplay((dynamic data) {
  print('Data from Presentation Display: $data');
