[pranay289]

I am getting Unknown mobile command "flutter:checkHealth". error while using this script assert.strictEqual(await driver.execute('flutter:checkHealth'), 'ok'); can anyone please help me regarding to this. I am using typescript for this.

Error

Here is my sample code

import * as find from "appium-flutter-finder"; 
import * as assert from "assert";
// import * as wdio from "webdriverio";
// import type { Options } from '@wdio/types'

// const config: Options.WebdriverIO = {
//     hostname: 'http://localhost',
//     port: 4444,
//     capabilities: {
//         browserName: 'Chrome'
//     }
// }
describe('Launch app', () => {
    it('Sigin screen', async () => {
        const buttonFinder = find.byValueKey('increment');

    //    assert.strictEqual(await driver.getElementText("Log in"),"Log in")
    //    const driver = await wdio.remote();
        assert.strictEqual(await driver.execute('flutter:checkHealth'), 'ok');
        await driver.elementClick(buttonFinder);
        // await driver.touchAction({
        //     action:'tap',
        // });
    //    await driver.touchAction({
    //     action: 'tap',
    //     element: { elementId: buttonFinder }
    //   });

    })
})

and also this script assert.strictEqual(await driver.execute('flutter:waitFor'), buttonPressed); not working same issue with this

From flutter side I have done this things

void main() async {
  enableFlutterDriverExtension();
 }

Is there anything I am missing?
