invocation_of_non_function
Details about the 'invocation_of_non_function' diagnostic produced by the Dart analyzer.
'{0}' isn't a function.
Description
#The analyzer produces this diagnostic when it finds a function invocation, but the name of the function being invoked is defined to be something other than a function.
Example
#
The following code produces this diagnostic because Binary is the name of
a function type, not a function:
dart
typedef Binary = int Function(int, int);
int f() {
return Binary(1, 2);
}
Common fixes
#Replace the name with the name of a function.
