Properties
-
check
→ ResultChecker<ERR, OK>
-
Creates a checker for this result.
Can be used to check if the result is an error or an ok value.
Example:
no setterinherited
-
err
→ ERR
-
Getter that will cast the result as an error.
If the result is ok, it will throw an exception.
You MUST CHECK if the result is an error before calling this getter.
no setterinherited
-
hashCode
→ int
-
The hash code for this object.
no setterinherited
-
isErr
→ bool
-
Getter that will check if this result is an error.
no setterinherited
-
isOk
→ bool
-
Getter that will check if this result is ok.
no setterinherited
-
ok
→ OK
-
Getter that will cast the result as ok.
If the result is an error, it will throw an exception.
You MUST CHECK if the result is ok before calling this getter.
no setterinherited
-
runtimeType
→ Type
-
A representation of the runtime type of the object.
no setterinherited
-
val
→ OK
-
final
Methods
-
map<ERR_OUT extends Object, OK_OUT extends Object>({required Result<ERR_OUT, OK_OUT> onErr(ERR), required Result<ERR_OUT, OK_OUT> onOk(OK)})
→ Result<ERR_OUT, OK_OUT>
-
Transforms this result into another result.
Takes two callback functions: one for the error case and one for the ok case.
Each callback function must return the same type of result.
Example:
inherited
-
mapFuture<ERR_OUT extends Object, OK_OUT extends Object>({required Future<Result<ERR_OUT, OK_OUT>> onErr(ERR), required Future<Result<ERR_OUT, OK_OUT>> onOk(OK)})
→ Future<Result<ERR_OUT, OK_OUT>>
-
Transforms this result into another result.
Takes two callback functions: one for the error case and one for the ok case.
Each callback function must return the same type of result.
Example:
inherited
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
toString()
→ String
-
