avoid_dynamic_calls
Method invocation or property access on a 'dynamic' target.
Description
#The analyzer produces this diagnostic when a member of a class is accessed on an expression whose type is dynamic
.
Example
#The following code produces this diagnostic because the getter length
is being invoked on s
, which has the type dynamic
:
dart
void f(dynamic s) {
s.length;
}
Common fixes
#Provide enough type information that the expression has a type other than dynamic
:
dart
void f(String s) {
s.length;
}
