arcgis 触屏实现键盘模拟

大家知道arcgis 键盘可以操作地图的前进后退， 我碰到一个需求需要在触屏面板 去操作键盘事件

我发现arcgis 并没有提供相应的api，于是我构建了一个触屏可以操作键盘上下左右 前进后退的模拟类

```javascript

import {esriClass, esriClassName} from "../tool/EsriClass";

export enum KeyToNumber {

ArrowDown = 3,

ArrowLeft = 0,

ArrowRight = 1,

ArrowUp = 2,

a = 6,

d = 7,

j = 5,

s = 9,

u = 4,

w = 8

}

class GamepadKeybordMonitorClass {

cameraControllerKeyboard: any;

constructor(){

}

async handleKeyDown(view : any, key: number) {

let disableMovements: any = {

ascend: true,

mode: "local",
