await_in_late_local_variable_initializer
The 'await' expression can't be used in a 'late' local variable's initializer.
Description
#The analyzer produces this diagnostic when a local variable that has the late
modifier uses an await
expression in the initializer.
Example
#The following code produces this diagnostic because an await
expression is used in the initializer for v
, a local variable that is marked late
:
Future<int> f() async {
late var v = await 42;
return v;
}
Common fixes
#If the initializer can be rewritten to not use await
, then rewrite it:
Future<int> f() async {
late var v = 42;
return v;
}
If the initializer can't be rewritten, then remove the late
modifier:
Future<int> f() async {
var v = await 42;
return v;
}
