Inside package:flame/gestures.dart you can find a whole set of mixins which can be included on your game class instance to be able to receive touch input events. Below you can see the full list of these mixins and its methods:

- TapDetector
  - onTap
  - onTapCancel
  - onTapDown
  - onTapUp

- SecondaryTapDetector
  - onSecondaryTapDown
  - onSecondaryTapUp
  - onSecondaryTapCancel

- DoubleTapDetector
  - onDoubleTap

- LongPressDetector
  - onLongPress
  - onLongPressStart
  - onLongPressMoveUpdate
  - onLongPressUp
  - onLongPressEnd

- VerticalDragDetector
  - onVerticalDragDown
  - onVerticalDragStart
  - onVerticalDragUpdate
  - onVerticalDragEnd
  - onVerticalDragCancel

- HorizontalDragDetector
  - onHorizontalDragDown
  - onHorizontalDragStart
  - onHorizontalDragUpdate
  - onHorizontalDragEnd
  - onHorizontalDragCancel

- ForcePressDetector
  - onForcePressStart
  - onForcePressPeak
  - onForcePressUpdate
  - onForcePressEnd

- PanDetector
  - onPanDown
  - onPanStart
  - onPanUpdate
  - onPanEnd
  - onPanCancel

- ScaleDetector
  - onScaleStart
  - onScaleUpdate
  - onScaleEnd

 - MultiTouchTapDetector
  - onTap
  - onTapCancel
  - onTapDown
  - onTapUp

 - MultiTouchDragDetector
  - onReceiveDrag

Many of these detectors can conflict with each other. For example, you can't register both Vertical and Horizontal drags, so not all of them can be used together.

It is also not possible to mix advanced detectors (MultiTouch*) with basic detectors as they will always win the gesture arena and the basic detectors will never be triggered. So for example, you can use both MultiTouchDragDetector and MultiTouchDragDetector together, but if you try to use MultiTouchTapDetector and PanDetector, no events will be triggered for the later.

Flame's GestureApi is provided byt Flutter's Gestures Widgets, including GestureDetector widget and RawGestureDetector widget, you can also read more about Flutter's gestures here.


class MyGame extends Game with TapDetector {
  // Other methods omitted

  void onTapDown(TapDownDetails details) {
    print("Player tap down on ${details.globalPosition.dx} - ${details.globalPosition.dy}");

  void onTapUp(TapUpDetails details) {
    print("Player tap up on ${details.globalPosition.dx} - ${details.globalPosition.dy}");

Tapable components

Flame also offers a simple helper to make it easier to handle tap events on PositionComponent. By adding the HasTapableComponents mixin to your game, and using the mixin Tapable on your components can override the following methods, enabling easy to use tap events on yours components.

  void onTapCancel() {}
  void onTapDown(TapDownDetails details) {}
  void onTapUp(TapUpDetails details) {}

Minimal component example:

import 'package:flame/components/component.dart';
import 'package:flame/components/mixins/tapable.dart';

class TapableComponent extends PositionComponent with Tapable {

  // update and render omitted

  void onTapUp(TapUpDetails details) {
    print("tap up");

  void onTapDown(TapDownDetails details) {
    print("tap down");

  void onTapCancel() {
    print("tap cancel");

class MyGame extends BaseGame with HasTapableComponents {
  MyGame() {


Flame provides a simple way to access Flutter's features regarding accessing Keyboard input events.

To use it, just add the KeyboardEvents mixin to your game class. When doing this you will need to implement the onKeyEvent method, this method is called every time a keyboard event happens, and it receives an instance of the Flutter class RawKeyEvent. This event can be used to get information about what occurred, like if it was a key down or key up event, and which key was pressed etc.

Minimal example:

import 'package:flame/game.dart';
import 'package:flame/keyboard.dart';
import 'package:flutter/services.dart';

class MyGame extends Game with KeyboardEvents {
  // update and render omitted

  void onKeyEvent(e) {
    final bool isKeyDown = e is RawKeyDownEvent;
    print(" Key: ${} - isKeyDown: $isKeyDown");

Flame provides a component capable of creating a virtual joystick for taking input for your game. It can be configure with a variaty of combinations, like using two sticks, or only one stick and some pressable buttons, and so on.

To use this feature. You need to create a JoystickComponent, configure it the way you want, and add it to your game.

To receive the inputs from the joystick component, you need to have a class which implements a JoystickListener, and that class needs to be added as an observer of the joystick component previous created. That implementer of the the JoystickListener could be any class, but one common practice is for it to be your component that will be controlled by the joystick, like a player component for example.

import 'package:flame/components/joystick/joystick_directional.dart';

import 'package:flame/gestures.dart';
import 'package:flutter/material.dart';

class MyGame extends BaseGame with MultiTouchDragDetector {
  final player = Player();

        opacityKnob: 0.8, // optional

  MyGame() {

  void onReceiveDrag(DragEvent drag) {

class Player extends Component implements JoystickListener {

  void render(Canvas canvas) {}

  void update(double dt) {}

  void joystickAction(JoystickActionEvent event) {
    // Do anything when click in action button.
    print('Action: $event');

  void joystickChangeDirectional(JoystickDirectionalEvent event) {
    // Do anything when interact with directional.
    print('Directional: $event');



    JoystickMoveDirectional directional,
    double intensity = 0.0,
    double radAngle = 0.0,

  enum JoystickMoveDirectional {


      int id,
      double intensity = 0.0,
      double radAngle = 0.0,
      ActionEvent event,

  enum ActionEvent { DOWN, UP, MOVE, CANCEL }
