Freelancer profile translated to English.

Description

My first steps in mobile development were through learning Flutter and Dart (Respectively, Google's Framework and programming language).

Flutter appeared to me as an incredible solution for cross-platform (Working on iOS & Android) and Web development.

This Framework offers 4 important advantages:

- Development time divided by 2 (Because it's cross-platform)

- Increased maintainability (1 source code to maintain for Android and iOS)

- Increased iteration speed (Fast to write and deploy)

- Performance similar to native languages (Important for fluidity)

The consequence? Development cost divided by two.

Flutter, try it and you'll love it.

Looking forward to discussing your amazing next Flutter projects,

Guillaume
