Network capture

Flutter implements its own network stack and does not use the underlying iOS or Android ones. Capturing Dart traffic therefore takes two things, and both are required:

1. The monitorNetwork launch option must be enabled. It is true by default — see configuration.
2. The Bugsee HTTP overrides handler must be installed explicitly. There is no default for this one:

  // This is required to let Bugsee intercept network requests
  HttpOverrides.global = Bugsee.defaultHttpOverrides;

We recommend adding this line into the main method of your application.

Why both

monitorNetwork controls Bugsee's network capture as a whole, including traffic issued by native platform code. Installing HttpOverrides.global is what routes your Dart traffic — anything built on dart:io's HttpClient, which includes package:http — through Bugsee in the first place. Leaving the overrides uninstalled means Dart requests are never seen, even though monitorNetwork defaults to on; setting monitorNetwork to false disables capture regardless of the overrides.
