WhatsApp not Launching IOS / Android

[lyntree]

Hi,

Wondering if you can help. I have tried running this on both simulators and android phone with debug and I have WhatsApp installed but its not launching, from the debugger on Android it showed the following, which made no sense when i clicked WhatsApp:

I/ViewRootImpl@736d65[MainActivity]( 6682): Relayout returned: old=(0,0,1440,3040) new=(0,0,1440,3040) req=(1440,3040)0 dur=9 res=0x1 s={true 528921267440} ch=false fn=3 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 0 I/ViewRootImpl@736d65[MainActivity]( 6682): ViewPostIme pointer 1

Where as on the simulator it shows for IOS:

[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method hasApp on channel br.com.thyagoluciano/flutter_launch) #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:154:7) <asynchronous suspension> #1 FlutterLaunch.hasApp (package:flutter_launch/flutter_launch.dart:24:12) <asynchronous suspension> #2 _MyAppState.whatsAppOpen (package:audiodamageradio/screens/Support.dart:22:21) <asynchronous suspension> [VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method hasApp on channel br.com.thyagoluciano/flutter_launch) #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:154:7) <asynchronous suspension> #1 FlutterLaunch.hasApp (package:flutter_launch/flutter_launch.dart:24:12) <asynchronous suspension> #2 _MyAppState.whatsAppOpen (package:audiodamageradio/screens/Support.dart:22:21) <asynchronous suspension>

If you could advise, what might be the issue that would be brilliant. Code is pretty much the same as the example I've added to the application but unsure if i'm missing any dependencies.

Kindest Regards,
