The community is finally at its first apex. I tried it this past weekend, and the VSCode setup was so sexy and easy to get started. I dropped React-Native in a heart beat, even losing a few weeks of work.
The biggest gripe I have with React-Native is the many JS packages on npm that we can't use due to how the code is exported. It's a huge hack job, which Flutter absolutely destroyed by having everything I needed as a package that just worked.
One thing I'm looking at on Flutter, is how their public packages age. If I can't use a 3 year old package on modern day Flutter, there will be some big problems coming soon.
