What is the future of flutter?

An extremely bright one.

The key component that would allow Flutter to get a lot of attention is the fact that it paints everything on the screen instead of using native OEM widgets and here is why it does that.

This would allow teams to bridge the gap between designers and developers and ship code frequently. This also means that you can have the flawless Flutter generated UI look exactly the same on all Android devices and all iOS devices. No more “This doesn’t look good on Samsung” issues.

If I were a beginner at developing mobile apps right now, I’d put my head down and create a lot of Flutter apps just out of excitement. It is THAT easy to learn. Related: "Flutter is awesome, but where do I start learning?"

A trending rumour right now is that Flutter would allow building apps for Fuchsia, Google’s next mobile/desktop OS(?). So if you get started with Flutter today, think of what all you could create if this rumour turns out to be true. Even if it doesn’t, you’d still be building quality mobile apps for both Android and iOS.

If you are a native Android/iOS app developer, I’ll strongly advise you to consider Flutter. There are 2 billion active Android devices and 1 billion active iOS devices in the world right now. For you, building for just one platform is resulting in a loss of a potential revenue of 33.33% (building for Android only) or 66.66% (building for iOS only).

What about ReactNative, you ask? That would probably co-exist with Flutter. No force in this world is strong enough to convince thousands of JS lovers to try out Flutter and make the switch completely.
