Hi, I Am Louis-Philippe

CEO Of Flutter Mapp

More than 5 years ago, I started with Flutter. I hated how much time people wasted on tutorials, so I created Flutter Mapp on YouTube. There was only one rule to follow: Never waste someone's time. I truly believe that creation should come from the heart! I'm extremely grateful to be able to help others reach their Flutter goals.
