please help me to fix this @plutoless

[plutoless]

could you pls provide a minimal reproducible project so that we can check what might go wrong?

[gathodeharrkirat]

hi... Have you found a solution yet ?

[LichKing-2234]

pls make sure the RtcEngine has been initializated.

Unhandled Exception: PlatformException(error, Please init RtcEngine first!, null, java.lang.RuntimeException: Please init RtcEngine first!

[LichKing-2234]

you can set minifyEnabled to false to confirm is the error from proguard?

this is the pubspec.yaml

name: newsimarnkapp description: A new Flutter project.

The following line prevents the package from being accidentally published to

pub.dev using pub publish. This is preferred for private packages.

publish_to: 'none' # Remove this line if you wish to publish to pub.dev

The following defines the version and build number for your application.

A version number is three numbers separated by dots, like 1.2.43

followed by an optional build number separated by a +.

Both the version and the builder number may be overridden in flutter

build by specifying --build-name and --build-number, respectively.

In Android, build-name is used as versionName while build-number used as versionCode.

Read more about Android versioning at https://developer.android.com/studio/publish/versioning

In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

Read more about iOS versioning at

https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

The following adds the Cupertino Icons font to your application.

Use with the CupertinoIcons class for iOS style icons.

cupertino_icons: ^1.0.2

dev_dependencies: flutter_test: sdk: flutter

For information on the generic Dart part of this file, see the

following page: https://dart.dev/tools/pub/pubspec

The following section is specific to Flutter.

flutter:

The following line ensures that the Material Icons font is

included with your application, so that you can use the icons in

the material Icons class.

uses-material-design: true

To add assets to your application, add an assets section, like this:

assets:

• assets/images/

• assets/loginback.png

  - assets/images/slider0.jpg

  - assets/images/slider1.jpg

  - assets/images/slider2.jpg

  An image asset can refer to one or more resolution-specific "variants", see

  https://flutter.dev/assets-and-images/#resolution-aware.

  For details regarding adding assets from package dependencies, see

  https://flutter.dev/assets-and-images/#from-packages

  To add custom fonts to your application, add a fonts section here,

  in this "flutter" section. Each entry in this list should have a

  "family" key with the font family name, and a "fonts" key with a

  list giving the asset and other descriptors for the font. For

  example:

  fonts:

• family: Como fonts:
  • asset: fonts/Como-Bold.ttf

    - asset: fonts/Schyler-Italic.ttf

    style: italic

    - family: Trajan Pro

    fonts:

    - asset: fonts/TrajanPro.ttf

    - asset: fonts/TrajanPro_Bold.ttf

    weight: 700

    #

    For details regarding fonts from package dependencies,

    see https://flutter.dev/custom-fonts/#from-packages

what error?

[LichKing-2234]

I will close this issue, you can reopen it if it still exists.

[Khatri7yash]

Mostly the problem is with resolution, Resolution more then 720p will result into black screen in some devices so decrease the resolution to 720p because in my case that helps me a lot... like now that black screen issue is solved.... Hoping my answer become helpful to you guys :)
