inherited
append(String name, Object value) → void
Adds a header value.
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
clear() → void
Removes all headers.
clone() → Headers
Creates a deep copy of this header collection.
contains(Object? element) → bool

inherited
every(bool test(MapEntry<String, String> element)) → bool

inherited
firstWhere(bool test(MapEntry<String, String> element), {MapEntry<String, String> orElse()?}) → MapEntry<String, String>
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, MapEntry<String, String> element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<MapEntry<String, String>> other) → Iterable<MapEntry<String, String>>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(MapEntry<String, String> element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
get(String name) → String?
Returns a merged value for name.
getAll(String name) → List<String>
Returns all values by name, preserving insertion order.
getSetCookie() → List<String>
Returns all set-cookie values.
has(String name) → bool
Returns whether name exists.
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(MapEntry<String, String> element), {MapEntry<String, String> orElse()?}) → MapEntry<String, String>
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(MapEntry<String, String> e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited
names() → Iterable<String>
Returns normalized header names in insertion order (without duplicates).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(MapEntry<String, String> combine(MapEntry<String, String> value, MapEntry<String, String> element)) → MapEntry<String, String>
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
set(String name, Object value) → void
Replaces all values for name with value.
singleWhere(bool test(MapEntry<String, String> element), {MapEntry<String, String> orElse()?}) → MapEntry<String, String>
The single element that satisfies test.
inherited
skip(int count) → Iterable<MapEntry<String, String>>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(MapEntry<String, String> value)) → Iterable<MapEntry<String, String>>

inherited
toList({bool growable = true}) → List<MapEntry<String, String>>
Creates a List containing the elements of this Iterable.
inherited
toMap() → Map<String, String>
Returns a map representation where duplicate values are merged by , .
