Good bye Android, it was good while it lasted

When I first started this blog, my goal was to document my journey in Android development. beginning-android-day-1 dates back to Sept 2017. It's been 7 years. However I won't work with Android anymore. Here's why. Android Back when I learned Android in 2017, it was pretty rough. I had to

Upgrading to flutter_svg 2.0.0

Because of https://www.wafrat.com/updating-major-versions-in-flutter/, I found myself upgrading my project, svg_drawing_animation (https://pub.dev/packages/svg_drawing_animation), to flutter_svg 2.0.0. And it was much harder than I thought. How can a developer so smart make it so hard for others? I

Updating major versions in Flutter

In the best case scenario, running flutter pub upgrade --major-versions does the trick. What happens though is that some packages restrict the major version we can upgrade to. % flutter pub upgrade --major-versions Resolving dependencies... (2.2s) No changes to pubspec.yaml!

Free synth plugins

Spitfire LABS has stopped working

Using Priority Queues on LeetCode in JavaScript and TypeScript to avoid `Time Limit Exceeded`
