Properties

authority → String

The authority component.

no setter, override

data → UriData?

Access the structure of a data: URI.

no setter, override

fragment → String

The fragment identifier component.

no setter, override

hasAbsolutePath → bool

Whether the URI has an absolute path (starting with '/').

no setter, override

hasAuthority → bool

Whether the URI has an authority component.

no setter, override

hasEmptyPath → bool

Whether the URI has an empty path.

no setter, override

hasFragment → bool

Whether the URI has a fragment part.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

hasPort → bool

Whether the URI has an explicit port.

no setter, override

hasQuery → bool

Whether the URI has a query part.

no setter, override

hasScheme → bool

Whether the URI has a scheme component.

no setter, override

host → String

The host part of the authority component.

no setter, override

isAbsolute → bool

Whether the URI is absolute.

no setter, override

isDisposed → bool

Flag which returns true if you called the dispose method. It is useful when you want to safely do some operations on the Watcher without getting an exception if it gets disposed.

no setter, inherited

origin → String

Returns the origin of the URI in the form scheme://host:port for the schemes http and https.

no setter, override

path → String

The path component.

no setter, override

pathSegments → List<String>

The URI path split into its segments.

no setter, override

port → int

The port part of the authority component.

no setter, override

query → String

The query component.

no setter, override

queryParameters → Map<String, String>

The URI query split into a map according to the rules specified for FORM post in the HTML 4.01 specification section 17.13.4.

no setter, override

queryParametersAll → Map<String, List<String>>

Returns the URI query split into a map according to the rules specified for FORM post in the HTML 4.01 specification section 17.13.4.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

safeMode → bool

safeMode if enabled will not allow any setting of value or notifying any listeners if the Watcher isDisposed

final, inherited

scheme → String

The scheme component of the URI.

no setter, override

stream → Stream<Uri>

Converts the Watcher into a Stream. This stream emits values whenever the value changes. The use of distinct ensures that consecutive duplicate values are filtered out, thus the stream only emits when the value actually changes.

no setter, inherited

userInfo → String

The user info part of the authority component.

no setter, override

v ↔ Uri

Equivalent to the getter value but in shorter syntax.

getter/setter pair, inherited

value ↔ Uri

The current value stored in this watcher.

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

debounce(Duration duration, void action(Uri value)) → VoidCallback

Registers a debounced callback which is invoked only after the notifier's value is stable for the specified duration.

inherited

dispose() → void

Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).

inherited

isScheme(String scheme) → bool

Whether the scheme of this Uri is scheme.

override

normalizePath() → Uri

Returns a URI where the path has been normalized.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

onChange(void action(Uri value)) → VoidCallback

Registers a callback to be invoked whenever the ValueNotifier's value changes.

inherited

refresh() → void

Rebuilds and trigger any listeners of any WatchValue or watch attached to that Watcher.

inherited

removeFragment() → Uri

Creates a Uri that differs from this only in not having a fragment.

override

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

inherited

replace({String? scheme, String? userInfo, String? host, int? port, String? path, Iterable<String>? pathSegments, String? query, Map<String, dynamic>? queryParameters, String? fragment, bool refresh = true}) → Uri

Creates a new Uri based on this one, but with some parts replaced.

override

resolve(String reference) → Uri

Resolve reference as an URI relative to this.

override

resolveUri(Uri reference) → Uri

Resolve reference as a URI relative to this.

override

setWithoutNotify(Uri newValue) → void

inherited

toFilePath({bool? windows}) → String

Creates a file path from a file URI.

override

toString() → String

A string representation of this object.

inherited

updateIf(bool condition(Uri), Uri newValue) → void

Updates the ValueNotifier's value to newValue if condition returns true.

inherited

updateOnAction<R>(R action()) → R

Will notifyListeners after a specific action has been made, and optionally return a result R of certain type.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
