avoid_global_state

Avoid top-level and static mutable variables.

Top-level variables can be modified from anywhere, which leads to hard to debug applications.

Prefer using a state management solution.

Example

BAD:

var globalMutable = 0; // LINT

class Test {
  static int globalMutable = 0; // LINT
}

GOOD:

final globalFinal = 1;
const globalConst = 1;

class Test {
  static const int globalConst = 1;
  static final int globalFinal = 1;
}
