avoid_ annotating_ with_ dynamic
Avoid annotating with dynamic
when not required.
Details
#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;
}

rule, add
avoid_annotating_with_dynamic
