avoid_final_parameters

Avoid final for parameter declarations.

AVOID declaring parameters as final.

Declaring parameters as final can lead to unnecessarily verbose code, especially when using the "parameter_assignments" rule.

BAD:

void goodParameter(final String label) { // LINT  print(label); } 

GOOD:

void badParameter(String label) { // OK  print(label); } 

BAD:

void goodExpression(final int value) => print(value); // LINT 

GOOD:

void badExpression(int value) => print(value); // OK 

BAD:

[1, 4, 6, 8].forEach((final value) => print(value + 2)); // LINT 

GOOD:

[1, 4, 6, 8].forEach((value) => print(value + 2)); // OK 

The avoid_final_parameters lint is incompatible with the following rules:

• prefer_final_parameters

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

linter:  rules:  - avoid_final_parameters 

If you're instead using the YAML map syntax to configure linter rules, add avoid_final_parameters: true under linter > rules:

linter:  rules:  avoid_final_parameters: true
