Filtering application logs

Stanislav Ilin - Nov 14 '22 - - Dev Community

🚀 New talker feature in 2.1.0 release is filtering logs, exceptions and errors. Now I want to tell you how it works.

There can be a lot of logs in a large application. Working with network via http, local storage, controllers, exceptions, errors, verbose info, etc.

👀 Sometimes it becomes difficult to track something very important. And at this moment, the talker update is rushing to your aid.

⚙️ Filtering data with Talker

Let's imagine that there are a lot of logs in your application

Talker logs

But our interest is to see only navigation logs.
How we can make it?

Talker logs selected

Add filter to your Talker constructor, or set it by configure() method

  final talker = Talker(
    filter: BaseTalkerFilter(
      types: [TalkerRouteLog],
    ),
  );
Enter fullscreen mode Exit fullscreen mode
  final talker = Talker();
  talker.configure(
    filter: BaseTalkerFilter(
      types: [TalkerRouteLog],
    ),
  );
Enter fullscreen mode Exit fullscreen mode

types: - log types driven by Talker package or your custom logs that you create. How I can make custom log?

Result:

But, how can I make it if I do not know what type of log is it?
Talker can do it 🙂 Use titles: filed of filter

  final talker = Talker(
    filter: BaseTalkerFilter(
      titles: ['ROUTE'],
    ),
  );
Enter fullscreen mode Exit fullscreen mode

Result will be same as of types: [TalkerRouteLog]
