Methods

addError(Object error, [StackTrace? stackTrace]) → void
inherited
addListener(GetStream<String?> rxGetx) → void
This is an internal method. Subscribe to changes on the inner stream.
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
allMatches(String string, [int start = 0]) → Iterable<Match>?

Available on Rx<String?>, provided by the RxnStringExt extension

bindStream(Stream<String?> stream) → void
Binds an existing Stream<T> to this Rx
inherited
call([String? v]) → String?
updates the value to null and adds it to the Stream. Even with null-safety coming, is still an important feature to support, as call() doesn't accept null values. For instance, InputDecoration.errorText has to be null to not show the "error state".
inherited
close() → void
Closes the subscriptions for this Rx, releasing the resources.
inherited
compareTo(String other) → int
Compares this object to another object.
override
compareTo(String other) → int?

Available on Rx<String?>, provided by the RxnStringExt extension

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 RxnStringExt extension

Returns true if this string contains a match of other:
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:
endsWith(String other) → bool?

Available on Rx<String?>, provided by the RxnStringExt extension

Returns true if this string ends with other. For example:
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
indexOf(Pattern pattern, [int start = 0]) → int?

Available on Rx<String?>, provided by the RxnStringExt 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:
lastIndexOf(Pattern pattern, [int? start]) → int?

Available on Rx<String?>, provided by the RxnStringExt extension

Returns the starting position of the last match pattern in this string, searching backward starting at start, inclusive:
listen(void onData(String?), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<String?>
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?

Available on Rx<String?>, provided by the RxnStringExt extension

Matches this pattern against the start of string.
override
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 RxnStringExt extension

Pads this string on the left if it is shorter than width.
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.
padRight(int width, [String padding = ' ']) → String?

Available on Rx<String?>, provided by the RxnStringExt 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
Makes a direct update of value adding it to the Stream useful when you make use of Rx for custom Types to referesh your UI.

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
toJson() → dynamic
Returns the json representation of value.
inherited
toLowerCase() → String?

Available on Rx<String?>, provided by the RxnStringExt extension

Converts all characters in this string to lower case. If the string is already in all lower case, this method returns this.
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 RxnStringExt extension

Converts all characters in this string to upper case. If the string is already in all upper case, this method returns this.
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 RxnStringExt extension

Returns the string without any leading and trailing whitespace.
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 RxnStringExt extension

Returns the string without any leading 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 RxnStringExt extension

Returns the string without any trailing whitespace.
trimRight() → String

Available on Rx<String>, provided by the RxStringExt extension

Returns the string without any trailing whitespace.
update(void 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).
