unnecessary_ string_ interpolations
Unnecessary use of string interpolation.
Description
#
The analyzer produces this diagnostic when a string literal contains a
single interpolation of a
String
-valued variable and no other
characters.
Example
#The following code produces this diagnostic because the string literal contains a single interpolation and doesn't contain any character outside the interpolation:
String f(String s) => '$s';
Common fixes
#Replace the string literal with the content of the interpolation:
String f(String s) => s;
