variable_pattern_keyword_in_declaration_context
Variable patterns in declaration context can't specify 'var' or 'final' keyword.
Description
#The analyzer produces this diagnostic when a variable pattern is used within a declaration context.
Example
#The following code produces this diagnostic because the variable patterns in the record pattern are in a declaration context:
dart
void f((int, int) r) {
var (var x, y) = r;
print(x + y);
}
Common fixes
#Remove the var
or final
keyword(s) within the variable pattern:
dart
void f((int, int) r) {
var (x, y) = r;
print(x + y);
}
