bug: platform resume won't trigger change

[loopezz]

Bug Report

Ionic version:

[x] 4.4.0

Current behavior: View won't get automatically updated after setting new values inside platform.resume.subscribe function. However, the view will be updated after a minimal touch on the screen of the device.

Expected behavior: Automatically trigger an change update after setting new values inside platform.resume.subscribe function.

Workaround: Using ngZone.run inside platform.resume.subscribe function will solve this issue, but I guess it shouldn't be needed.

Steps to reproduce:

1. Checkout the related code
2. Install app on a device or simulator
3. Run the app
4. Click the device's "Home" button
5. Open the app from background

Related code: https://github.com/loopezz/async-update.git

this.platform.resume.subscribe(() => {
  // this.ngZone.run(() => {
    // Text will not be visible updated without running inside ngZone
    this.fakeHttp.updateText();
  // });
});

Thanks for your issue! It depends on your app. You need to run it with ngZone to call change detection. In your case you have to do it. It has nothing to do with Ionic what you describe
