What makes Flutter unique?

Flutter is different than most other options
for building mobile apps because it doesn’t rely
on web browser technology nor the set of widgets
that ship with each device. Instead, Flutter uses
its own high-performance rendering engine to draw widgets.

In addition, Flutter is different because it only
has a thin layer of C/C++ code. Flutter implements
most of its system (compositing, gestures, animation,
framework, widgets, etc) in Dart (a modern,
concise, object-oriented language) that developers
can easily approach read, change, replace, or remove.
This gives developers tremendous control over the system,
as well as significantly lowers the bar to approachability
for the majority of the system.

Should I build my next production app with Flutter?
