Hi, my name is Mateus Rodrigues Costa 🫡, aka MateusRodCosta. On some gaming-related contexts, I tend to prefer to use Matias as a nickname due to its etymological relationship to my real name.

• 👨 I'm a 🇧🇷 Brazilian 👨‍💻 Programmer currently focusing on 📱 mobile apps development. I have the most experience with Flutter (using Dart) but I also have been investing some time in learning Jetpack Compose (using Kotlin).
• In Flutter, I personally prefer doing state management with Provider for simple use cases and BLoC for more complex apps.
• ⭐ My currently most noteworthy creations are Save Locally: Share2Storage (a small utility made with Jetpack Compose that allows redirecting a file shared via the system Share system so it can be saved with the system native file picker) and Vidya Music (a Flutter frontend acting as a player for VIP Aersia, a very popular video game music playlist that has been on the web for more than 14 years).

I am currently author or maintainer of the following projects:

• 📱 Mobile Apps:
  • Save Locally: Share2Storage (Jetpack Compose , Android ) (Google Play , F-Droid ) - Using an app that doesn't allow Saving but allows Sharing? No problem!
  • Vidya Music (Flutter , Android ) (Google Play , F-Droid ) - A player for the Vidya Intarweb Playlist (aka VIP Aersia)
• 🖥️ Desktop Apps:
  • Stereotyping (GTK + Rust , Linux ) - A GTK4 front-end to libmagic
• ⚙️ Miscellaneous projects:
  • Default Workspace (GNOME Extensions ) - Switches to the specified workspace on login
  • 🖼️ bign-handheld-thumbnailer(Rust , Linux ) - A thumbnailer for Nintendo handheld systems (Nintendo DS and 3DS) roms and files
• 📦 Packaging:
  • ChibiTracker (manifest) (Flathub ) - ChibiTracker is a portable IT (Impulse Tracker) clone
  • Digital: A Love Story (manifest) (Flathub ) - A computer mystery/romance set five minutes into the future of 1988
  • don't take it personally, babe, it just ain't your story (manifest) (Flathub ) - A spiritual sequel of sorts to Digital: A Love Story, set in a prestigious private high school, and on the social networks of 2027
  • bign-handheld-thumbnailer (spec) (COPR) - A thumbnailer for Nintendo handheld systems (Nintendo DS and 3DS) roms and files. COPR available for Fedora 39, 40 and Rawhide, in x86_64 and Aarch64 variants

• Fedora Linux Contributor since 2021.
  • ✒️ I usually write for Fedora Magazine, mainly about Fedora Silverblue and sometimes technical tutorials. My latest article is called Authselect in Fedora Linux 40: Migrating to the new “local” profile, you can see more of them here,.
• 🗃 Due to the death of Flash and the death of the Cartoon Network websites (being turned into redirects to the CN section on Max), I have been working on slowly archiving the Brazilian variants of old Cartoon Network games (mainly focusing on Shockwave and Flash formats) into Flashpoint
  • 🗃 As a side effect I have helped on adding the pt-BR versions (including creating the lost translations) into the web ports of the Cartoon Cartoon Summer Resort and Scooby Doo Hollywood Horror games. (Hosted version)
