avoid_annotating_with_dynamic

Avoid annotating with dynamic when not required.

AVOID annotating with dynamic when not required.

As dynamic is the assumed return value of a function or method, it is usually not necessary to annotate it.

BAD:

dynamic lookUpOrDefault(String name, Map map, dynamic defaultValue) {  var value = map[name];  if (value != null) return value;  return defaultValue; } 

GOOD:

lookUpOrDefault(String name, Map map, defaultValue) {  var value = map[name];  if (value != null) return value;  return defaultValue; } 

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

linter:  rules:  - avoid_annotating_with_dynamic 

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

linter:  rules:  avoid_annotating_with_dynamic: true
