What the hack is SOLID? (part 1)
According to Ahsan Ali, the SOLID principles are important for software development as they facilitate good architecture and maintainability. The Single Responsibility Principle, for example, encourages developers to create classes with a single responsibility so that they are easier to maintain and harder to break. The Open Close Principle states that developers should be able to extend their code without changing existing functions. Utilizing abstraction and inheritance can make the code more readable and maintainable.

Developing with Flutter put my Mac's system data at 220gb?
My Macbook Pro 2020 is 18 mos old and the only thing I've used it for is developing Flutter apps, mostly with Android Studio but also occasionally with VSCode. I do use it for related team work, like Slack and Teams.I just checked its available storage and its "system data" used is 240gb. I did the usual google for freeing up storage and ran a cleaning up, but that only freed up 20gb.In there a common culprit for consuming system data storage on a Mac when developing with Flutter? Something that would take up that much storage?I don't have any movies or photos on the Mac and don't use it for email. The only other thing I use it for is YouTube (mostly to watch Flutter tutorials, etc.)
