Geeting below error while installing WebRTC based app on Android but its working fine on Browser.

Getting below error:

Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_webrtc-0.8.4/lib/src/native/rtc_data_channel_impl.dart:16:7: Error: The non-abstract class 'RTCDataChannelNative' is missing implementations for these members:

• RTCDataChannel.bufferedAmount
• RTCDataChannel.id Try to either
• provide an implementation,
• inherit an implementation from a superclass or mixin,
• mark the class as abstract, or
• provide a 'noSuchMethod' implementation.

class RTCDataChannelNative extends RTCDataChannel { ^^^^^^^^^^^^^^^^^^^^ ../../../Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/webrtc_interface-1.0.3/lib/src/rtc_data_channel.dart:79:12: Context: 'RTCDataChannel.bufferedAmount' is defined here. int? get bufferedAmount; ^^^^^^^^^^^^^^ ../../../Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/webrtc_interface-1.0.3/lib/src/rtc_data_channel.dart:74:12: Context: 'RTCDataChannel.id' is defined here. int? get id; ^^

You need to upgrade your dependencies to fix this issue, so run:

flutter pub upgrade
