unnecessary_this

Don't access members with this unless avoiding shadowing.

This rule is available as of Dart 2.0.

Rule sets: recommended, flutter

This rule has a quick fix available.

From Effective Dart:

DON'T use this when not needed to avoid shadowing.

BAD:

class Box {
  int value;
  void update(int newValue) {
    this.value = newValue;
  }
}

GOOD:

class Box {
  int value;
  void update(int newValue) {
    value = newValue;
  }
}

GOOD:

class Box {
  int value;
  void update(int value) {
    this.value = value;
  }
}

To enable the unnecessary_this rule, add unnecessary_this under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - unnecessary_this
