cast_to_non_type
The name '{0}' isn't a type, so it can't be used in an 'as' expression.
Description
#The analyzer produces this diagnostic when the name following the as in a
cast expression is defined to be something other than a type.
Example
#The following code produces this diagnostic because x is a variable, not
a type:
dart
num x = 0;
int y = x as x;Common fixes
#Replace the name with the name of a type:
dart
num x = 0;
int y = x as int;
