unnecessary_ brace_ in_ string_ interps
Unnecessary braces in a string interpolation.
Description
#The analyzer produces this diagnostic when a string interpolation with braces is used to interpolate a simple identifier and isn't followed by alphanumeric text.
Example
#
The following code produces this diagnostic because the interpolation
element
${s}
uses braces when they are not necessary:
String f(String s) {
return '"${s}"';
}
Common fixes
#Remove the unnecessary braces:
String f(String s) {
return '"$s"';
}
