Constructors

RxString(String initial)

Properties

codeUnits → List<int>: Available on Rx<String>, provided by the RxStringExt extension
Returns an unmodifiable list of the UTF-16 code units of this string.
no setter
firstRebuild ↔ bool: getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
isDisposed → bool: no setterinherited
isEmpty → bool: Available on Rx<String>, provided by the RxStringExt extension
Returns true if this string is empty.
no setter
isNotEmpty → bool: Available on Rx<String>, provided by the RxStringExt extension
Returns true if this string is not empty.
no setter
listenersLength → int: no setterinherited
runes → Runes: Available on Rx<String>, provided by the RxStringExt extension
Returns an Iterable of Unicode code-points of this string.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sentToStream ↔ bool: getter/setter pairinherited
stream → Stream<String>: no setterinherited
string → String: Same as toString() but using a getter.
no setterinherited
subject → StreamController<String>: no setterinherited
value ↔ String: The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.

Methods

addError(Object error, [StackTrace? stackTrace]) → void: inherited
addListener(StateUpdateCallback listener) → Disposer: Register a closure to be called when the object notifies its listeners.
inherited
allMatches(String string, [int start = 0]) → Iterable<Match>: Available on Rx<String>, provided by the RxStringExt extension
allMatches(String string, [int start = 0]) → Iterable<Match>: Matches this pattern against the string repeatedly.
override
bindStream(Stream<String> stream) → void: Binds an existing Stream<T> to this Rx
inherited
call([String? v]) → String: Makes this Rx looks like a function so you can update a new value using rx(someOtherValue). Practical to assign the Rx directly to some Widget that has a signature ::onChange( value )
inherited
close() → void: Close the Rx Variable
inherited
compareTo(String other) → int: Compares this object to another object.
override
compareTo(String other) → int: Available on Rx<String>, provided by the RxStringExt extension
contains(Pattern other, [int startIndex = 0]) → bool: Available on Rx<String>, provided by the RxStringExt extension
Returns true if this string contains a match of other:
containsListener(StateUpdateCallback listener) → bool: inherited
dispose() → void: inherited
endsWith(String other) → bool: Available on Rx<String>, provided by the RxStringExt extension
Returns true if this string ends with other. For example:
indexOf(Pattern pattern, [int start = 0]) → int: Available on Rx<String>, provided by the RxStringExt extension
Returns the position of the first match of pattern in this string
lastIndexOf(Pattern pattern, [int? start]) → int: Available on Rx<String>, provided by the RxStringExt extension
Returns the starting position of the last match pattern in this string, searching backward starting at start, inclusive:
listen(ValueChanged<String>? onData, {Function? onError, VoidCallback? onDone, bool? cancelOnError}) → StreamSubscription<String>: Calls callback with current value, when the value changes.
inherited
listenAndPump(void onData(String event), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<String>: Returns a StreamSubscription similar to listen, but with the added benefit that it primes the stream with the current value, rather than waiting for the next value. This should not be called in onInit or anywhere else during the build process.
inherited
map<R>(R mapper(String data)) → Stream<R>: inherited
matchAsPrefix(String string, [int start = 0]) → Match?: Matches this pattern against the start of string.
override
matchAsPrefix(String string, [int start = 0]) → Match?: Available on Rx<String>, provided by the RxStringExt extension
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
padLeft(int width, [String padding = ' ']) → String: Available on Rx<String>, provided by the RxStringExt extension
Pads this string on the left if it is shorter than width.
padRight(int width, [String padding = ' ']) → String: Available on Rx<String>, provided by the RxStringExt extension
Pads this string on the right if it is shorter than width. Return a new string that appends padding after this string one time for each position the length is less than width.
refresh() → void: inherited
removeListener(StateUpdateCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies.
inherited
replaceAll(Pattern from, String replace) → String: Available on Rx<String>, provided by the RxStringExt extension
Replaces all substrings that match from with replace.
reportAdd(StateUpdateCallback disposer) → void: inherited
reportRead() → void: inherited
split(Pattern pattern) → List<String>: Available on Rx<String>, provided by the RxStringExt extension
Splits the string at matches of pattern and returns a list of substrings.
startsWith(Pattern pattern, [int index = 0]) → bool: Available on Rx<String>, provided by the RxStringExt extension
Returns true if this string starts with a match of pattern.
substring(int startIndex, [int? endIndex]) → String: Available on Rx<String>, provided by the RxStringExt extension
Returns the substring of this string that extends from startIndex, inclusive, to endIndex, exclusive
toLowerCase() → String: Available on Rx<String>, provided by the RxStringExt extension
Converts all characters in this string to lower case. If the string is already in all lower case, this method returns this.
toString() → String: A string representation of this object.
inherited
toUpperCase() → String: Available on Rx<String>, provided by the RxStringExt extension
Converts all characters in this string to upper case. If the string is already in all upper case, this method returns this.
trigger(String v) → void: Following certain practices on Rx data, we might want to react to certain listeners when a value has been provided, even if the value is the same. At the moment, we ignore part of the process if we .call(value) with the same value since it holds the value and there's no real need triggering the entire process for the same value inside, but there are other situations where we might be interested in triggering this.
inherited
trim() → String: Available on Rx<String>, provided by the RxStringExt extension
Returns the string without any leading and trailing whitespace.
trimLeft() → String: Available on Rx<String>, provided by the RxStringExt extension
Returns the string without any leading whitespace.
trimRight() → String: Available on Rx<String>, provided by the RxStringExt extension
Returns the string without any trailing whitespace.
update(String fn(String? val)) → void: Uses a callback to update value internally, similar to refresh, but provides the current value as the argument. Makes sense for custom Rx types (like Models).

Operators

operator +(String val) → String: Available on Rx<String>, provided by the RxStringExt extension
operator ==(Object o) → bool: This equality override works for _RxImpl instances and the internal values.
