Top 10 Flutter Packages for 2020

Open-source has changed the way software is written and distributed. It has played an essential role in making software development easy, fun and more approachable. Flutter, being an open-source cross-platform mobile app development platform, has a thriving community with developers putting their efforts across the globe to make it more successful. It’s not just Google who is responsible to take Flutter further, it’s the community as well.

Mobile app developer community embraced Flutter so quick that there are a wealth of open-source packages for it in a very short time.

Just like libraries, packages reduce the development time frame as developers don’t need to perform development from scratch for trivial functionalities. Things like HTTP calls, image caching etc become easier if we’re using the right packages.

We have curated a list of top 10 Flutter libraries that provide tremendous support in Flutter app development. After conducting proper research, we have picked out the most useful Flutter packages for your reference.

Every Flutter developer must know about these listed packages:
