Touch gestures using Hammer.js including tapping and swiping downwards

Is there a way to use HammerJS in Angular Material to implement drag-down functionality that triggers an event?

I want the dragdown event, as shown in the image below on the gray bar just above the Facebook button. How can I achieve this?

Answer №1

To incorporate Hammer into your project, you need to make some changes in the main module.

import * as Hammer from 'hammerjs';

If you wish to customize the configuration, follow these steps:

import { HammerGestureConfig, HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';

Create a new class:

export class MyHammerConfig extends HammerGestureConfig {
  overrides = <any> {
    swipe: { direction: Hammer.DIRECTION_ALL },
  };
}

Then, use it as a provider:

providers: [
    {
      provide: HAMMER_GESTURE_CONFIG,
      useClass: MyHammerConfig,
    },
  ],

For an example, visit this link.

NOTE: If you are looking for (swipeDown), this might be what you need.
