> Most of our apps use React. When we first adopted React, we were pleased with the development productivity it provided, but sadly its initial performance was subpar in terms of start-up time, memory consumption, and responsiveness. After significant and complicated optimizations we reached performance benchmarks that were good enough, and yet we desired a new technology that was both fast and simple.
> To our delight, our very first prototype with Flutter easily exceeded our target benchmarks! Without any optimization whatsoever, our Flutter rewrite launched twice as fast as our original app, consumed less runtime memory, and felt more responsive and playful to use
