Dart can be classified into two categories such as non-nullable and nullable type. The nullable type has a particular operator, which can help the developer work smoothly. On the other hand, this type can consist of null or value.

Non-Nullable dart types only contain values, and nulls don’t permit. The hierarchy dart type has an object at the top and never at the bottom. The code estimates the never that aborts the program or throws exclusion.

analyzer: 
enable-experiment: 
- spread-collections

flutter channel dev

flutter upgrade

flutter --version

environment: sdk: ">=2.10.0-0 <3.0.0"
