After implementing the monitoring of a Flutter application, following all the paths in the directory and the necessary configuration points informed in the flutter plugin.
https://pub.dev/packages/dynatrace_flutter_plugin
After following the installation steps I'm getting the following below error :
../flutter/.pub-cache/hosted/pub.dartlang.org/dynatrace_flutter_plugin-2.237.0/lib/src/agent/http/http_client.dart:5:7:
Error: The non-abstract class 'DynatraceHttpClient' is missing implementations for these members:
- HttpClient.connectionFactory=
- HttpClient.keyLog=
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 DynatraceHttpClient implements HttpClient {
