Checkout our documentation for full reference. Include the following dependency in your pubspec.yaml:

dependencies:
  gleap_dio_interceptor: "^2.0.0"

Flutter v2 Support

If you are using Flutter < v3, please import the gleap_sdk as shown below:

dependencies:
  gleap_dio_interceptor:
    git:
      url: https://github.com/GleapSDK/gleap_dio_interceptor.git
      ref: flutter-v2

Version 2.0 requires gleap_sdk 19.0.0 or newer and dio 5.2.0 or newer.

Dio dio = Dio();
dio.interceptors.add(GleapDioInterceptor());

dio.get("https://example.com");

Add the interceptor after your other interceptors, so the logged duration covers the network request only.

What is logged

Each request is logged with its full url, method, start time, duration, request and response headers and bodies (JSON as JSON, form data as a summary of fields and file names, bodies capped at 150 KB). Requests that fail without a response are logged with the error. Stream responses are never read, and binary or streaming bodies are replaced by a marker. The interceptor never changes a request or response.

Gleap keeps the newest 30 requests. To keep sensitive data out of the logs, use Gleap.setNetworkLogPropsToIgnore(propsToIgnore: ['password', 'token']) (removes headers, JSON keys, form fields and query parameters with these names) and Gleap.setNetworkLogsBlacklist(blacklist: ['/internal/']) (skips requests whose url contains an entry). Authorization and cookie headers are always masked.
