This is Part 2 of a multi-part series where I discuss the brief history of Flutter. You can find Part 1 here.

Flutter 2.0: Sound Null Safety and Flutter Web in Stable Version

In the March of 2021, the Flutter team released an important release for Flutter developers called Flutter 2.0, which covered Null Safety features on the dart language.

This means developers can prevent null error crashes and other common reasons for apps to crash before they happen. They can handle all runtime null errors and app crashes caused in compile time. They can use the (? and !) operator sign if needed.

Adaption in Sound Null Safety

  • Sound Null Safety is a valuable and significant addition to the dart language.
  • Errors and common app crashes are caught during the app's development.
  • That helps to prevent app crashes and null errors on production.
  • More than 1,000 null safe packages are published in pub dev.
  • Dart, Flutter, Firebase, and Material teams also updated on Null safety.

Adaption in Web

  • Now Flutter Web is in a stable channel from the beta.
  • After this release, we can run our code on three different platforms named Android, iOS and Web.
  • The Flutter team focuses on performance and fidelity improvements in this stable Web release.
  • In the HTML renderer, they added a CanvasKit-based renderer.
  • Introduced Link widget for the web app.
