A Dio interceptor to submit telemetry data to Azure Application Insights

A Dio interceptor that sends request metrics to Azure Application Insights.

This package is inspired by a previous implementation for Firebase.

Usage #

final dio = Dio();
final insightsInterceptor = DioAzureApplicationInsightsInterceptor();
dio.interceptors.add(insightsInterceptor);

Additional information #

The interceptor will auto-configure itself if deployed on Azure and a connection to Application Insights is setup. Auto-configuration happens by reading the environment variable APPLICATIONINSIGHTS_CONNECTION_STRING.

Alternatively either a connection or an existing instance of TelemetryClient can be supplied.

If no parameters are supplied and the environment variable doesn't exist, the observer will not submit any logs (but also not produce any errors).

Note: The interceptor optionally supports injecting a custom HTTP client to submit telemetry data. Do not use the observed Dio instance as HTTP client for telemetry, because this would cause every telemetry item to again generate additional telemetry and thus spamming the logs.
