Formants dialogue in roguetui... also on web! Pesky timer resolutions, Cross-Origin-Opener-Policy, and a million other issues when debugging wasm->wasm->webaudio! #termui #termui_audio #dart #flutter

Hey #FlutterDev and #FlameEngine folks! I've just published an article on how I made it possible to build and run my game natively on the Stem Deck! Check it out: dev.to/erickzanardo...

Work in progress: started off trying to make chiptune dialogue work with text. This worked well on CLI / Flutter Windows, but WASM/Web was always just... wrong. So I tried another path: audio atlases, and taking a note from the Celeste folks. #dart #flutter #tui

27 July

"chiptune" that I wasn't happy with.

25 July

Something I've been working on with the termui / termui_audio / termui_flutter packages. Recorded from Flutter Web + WASM, but also runs in a console. #dart #flutter

jtmcdole.github.iotermui_audio_exampleA new Flutter project.

21 July

Added soloud to termui: termui_audio. CLI uses dart:ffi to soloud libs. Web/Windows/Mac/Linux has a wrapper to flutter_soloud. Demo: jtmcdole.github.io/termui_audio/

8 July

Sparklines and improvements to LinearProgressIndicator added to termui. I wanted to emulate btop's awesome graphs, so: 1. braille and quads 2. added "width" to the bars if you want with different fills. 3. Added "stops" for all bars. 4. Vertical options!

6 July

termui 0.7.1 - pty support, some more debug tools to show layers / widget boundaries, resizing, focus.. and mouse clicks. KTTY support would be the next thing to add, but I'm going to finish my e-reader and work on a game or something.

Madness, thy name is idle hands. #termui #dart #flutter

termui is getting platform views....

pub.devpty2 | Dart packagePty2 for Dart and Flutter. Provides the ability to create processes with pseudo terminal file descriptors.

Updated pty2 to work better on windows and linux: 70MB/s ConPTY, 200MB/s Linux! Arena allocation, native finalizers, and more tests... also a new home in termui monorepo.

20 June

I was writing a immersive cli epub reader + audiobook playback "for fun" and I kept copying the same library around. I thought I'd make it into a package, but before release I spent some time with Antigravity and got just a little carried away... docker+flutter+agy cli is a pretty great combo.

20 June

Very much inspired by Charm / Bubble Tea / all the other great terminal UI's out there, but for Dart. Also works in Flutter if you use the termui_flutter package. This uses canvas.drawRawAtlas() for faster rendering that a full blown PTY emulator.

Cloud Functions and Admin SDK for Firebase now supports Dart as an experimental feature 🎯 This means Flutter developers can use the same programming language throughout their whole stack and share logic between the frontend and backend.

Then Google launched Gemini CLI Conductor. I spent the last few weekends really trying to pull the spaghetti out of my old code and make it available in package form. It's about 50/50 code to tests, with a lot of that being storage options. Take a look if you've got fullstack Flutter/Dart.

Read this article and I feel like we should tax unrealized gains when they are effectively realized through "buy, borrow, die" strategies. If you sell - great, use it against capital gains. Unfortunately we live in a lottery society, hoping to be the next billionaire.

Side note: I think we absolutely should do more on the waste and fraud on the spend side of the vote-revenue-spend triangle.
