Result class
Result represents a Database.query's result and provides an Iterable interface for the results to be consumed.
Please note that this iterator should be closed manually if not all Rows are consumed.

Methods
-
any(
bool test(Row element)) → bool -
Checks whether any element of this iterable satisfies
test
.inherited -
cast<
R> () → Iterable< R> -
A view of this iterable as an iterable of
R
instances.inherited -
close(
) → void - Close this iterables iterator.
-
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element
.inherited -
elementAt(
int index) → Row -
Returns the
index
th element.inherited -
every(
bool test(Row element)) → bool -
Checks whether every element of this iterable satisfies
test
.inherited -
expand<
T> (Iterable< T> toElements(Row element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(Row element), {Row orElse()?}) → Row -
The first element that satisfies the given predicate
test
.inherited -
fold<
T> (T initialValue, T combine(T previousValue, Row element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< Row> other) → Iterable<Row> -
Creates the lazy concatenation of this iterable and
other
.inherited -
forEach(
void action(Row element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(Row element), {Row orElse()?}) → Row -
The last element that satisfies the given predicate
test
.inherited -
map<
T> (T toElement(Row e)) → Iterable< T> -
The current elements of this iterable modified by
toElement
.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
Row combine(Row value, Row element)) → Row -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
singleWhere(
bool test(Row element), {Row orElse()?}) → Row -
The single element that satisfies
test
.inherited -
skip(
int count) → Iterable< Row> -
Creates an Iterable that provides all but the first
count
elements.inherited -
skipWhile(
bool test(Row value)) → Iterable< Row> -
Creates an
Iterable
that skips leading elements whiletest
is satisfied.inherited -
take(
int count) → Iterable< Row> -
Creates a lazy iterable of the
count
first elements of this iterable.inherited -
takeWhile(
bool test(Row value)) → Iterable< Row> -
Creates a lazy iterable of the leading elements satisfying
test
.inherited -
toList(
{bool growable = true}) → List< Row> -
Creates a List containing the elements of this Iterable.
inherited
-
toSet(
) → Set< Row> -
Creates a Set containing the same elements as this iterable.
inherited
-
toString(
) → String -
Returns a string representation of (some of) the elements of
this
.inherited -
where(
bool test(Row element)) → Iterable< Row> -
Creates a new lazy Iterable with all elements that satisfy the
predicate
test
.inherited -
whereType<
T> () → Iterable< T> -
Creates a new lazy Iterable with all elements that have type
T
.inherited
Operators
-
operator ==(
Object other) → bool -
