flutter_tvos 1.0.1

Platform detection and utilities for Flutter apps running on Apple TV (tvOS). Provides runtime checks for tvOS, device info, and capability queries.

flutter_tvos

Platform detection and utilities for Flutter apps running on Apple TV (tvOS).

Part of the flutter-tvos project — an open-source Flutter embedder for Apple TV.

Features

• Detect if the app is running on tvOS
• Query tvOS version, device model, and machine identifier
• Check device capabilities: 4K, HDR, multi-user support
• Get display resolution
• Synchronous API — powered by dart:ffi, zero async overhead

Getting Started

Add flutter_tvos to your pubspec.yaml:

dependencies:
  flutter_tvos: ^1.0.0

Usage

import 'package:flutter_tvos/flutter_tvos.dart';

// Check if running on tvOS
if (TvOSInfo.isTvOS) {
  print('Running on Apple TV!');
}

// Get platform details
final version = TvOSInfo.tvOSVersion;   // "18.4"
final model   = TvOSInfo.deviceModel;   // "Apple TV"
final machine = TvOSInfo.machineId;     // "AppleTV14,1"

// Check capabilities
final is4K      = TvOSInfo.supports4K;       // true/false
final isHDR     = TvOSInfo.supportsHDR;      // true/false
final multiUser = TvOSInfo.supportsMultiUser; // true (tvOS 14+)

// Display info
final width  = TvOSInfo.displayWidth;      // 3840
final height = TvOSInfo.displayHeight;     // 2160
final res    = TvOSInfo.displayResolution; // "3840x2160"

// Check simulator
final isSim = TvOSInfo.isSimulator; // true/false

Adaptive UI Example

Widget build(BuildContext context) {
  if (TvOSInfo.isTvOS) {
    return TvLayout(child: content);    // TV-optimized layout
  }
  return MobileLayout(child: content); // Standard mobile layout
}

Remote Control (Siri Remote)

flutter_tvos wires the Apple TV remote to Flutter's standard focus system. Swipes and button presses become keyboard events (arrowLeft/Right/Up/Down, select, etc.) which flow through Focus/Shortcuts/Actions exactly like arrow keys on a physical keyboard would.

One-line setup: use runTvApp in place of runApp:

import 'package:flutter_tvos/flutter_tvos.dart';

void main() => runTvApp(const MyApp());

On iOS/Android runTvApp is a plain passthrough — the same main.dart works across all platforms.

What works out of the box

• Swipes Up/Down/Left/Right on Siri Remote → arrow keys
• Select button → LogicalKeyboardKey.enter — activates focused buttons / list items through Flutter's default ActivateIntent binding, matching Flutter Android / flutter-tizen behavior
• Menu button → flutter/navigation popRoute → Navigator.maybePop (same as Android's physical back button)
• Play/Pause → LogicalKeyboardKey.mediaPlayPause
• Long-press in a direction → auto-repeat arrow key at ~80 ms intervals
• External game controllers (MFi) with a directional pad
• Lock-screen media commands (play, pause, seek, stop, toggle) are forwarded through flutter/keyevent so any widget reacting to LogicalKeyboardKey.mediaPlay / mediaPause / mediaFastForward / mediaRewind / mediaStop / mediaPlayPause is triggered with no app-level wiring

Tuning

All tuning lives on TvRemoteConfig. Assigning a new config to TvRemoteController.instance.config ships the values to the native engine plugin (via a method-channel call); mutations take effect on the next input event.

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  TvRemoteController.instance.config = const TvRemoteConfig(
    shortSwipeThreshold: 0.4,                         // raw-listener swipe threshold
    fastSwipeThreshold: 0.6,                          // "fast" flag threshold
    dpadDeadZone: 0.6,                                // off-center distance for click bias
    continuousSwipeMoveThreshold: 4,                  // consecutive moves before auto-repeat
    keyRepeatInitialDelay: Duration(milliseconds: 450),
    keyRepeatInterval: Duration(milliseconds: 100),
  );
  runTvApp(const MyApp());
}

All fields have sensible defaults so apps that never touch config behave identically to the stock configuration.

Raw touch listener (video players, custom swipe zones)

TvRemoteController.instance.addRawListener((event) {
  if (event.phase == TvRemoteTouchPhase.move && isInPlayerArea(event)) {
    seekVideo(event.x);
  }
});

Swipe listener (high-level direction + magnitude)

For consumers that just want "user swiped left/right/up/down" without hand-rolling a detector, subscribe at the swipe-event level:

TvRemoteController.instance.addSwipeListener((event) {
  if (event.direction == SwipeDirection.right && event.isFast) {
    seekVideo(seconds: 30);
  }
});

SwipeEvent carries direction (left/right/up/down), magnitude (max(|dx|, |dy|) in normalized [-1, 1] view space), and isFast (true when magnitude crosses fastSwipeThreshold from TvRemoteConfig).

Raw addRawListener callbacks still receive every touch point in parallel — the two layers are independent.
