Abraham Lincoln said “Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” The Mobile development is exactly like that. Being a mobile app developer is not only about developing apps, but a major chunk of our day-to-day work is spent on debugging the bugs in those apps. And to speed up the debugging skills, we need more polished tools like the axe. And FB Flipper is one of the best tools for mobile app debugging. Flipper is a platform for debugging iOS, Android and React Native apps. Visualize, inspect, and control your apps from a simple desktop interface. Use Flipper as is or extend it using the plugin API. In this talk, I will show you some features of the Flipper, and share you how it can help you with your mobile app development and debugging.
