Finder class - flutter_test library

Constructors

Finder({bool skipOffstage = true}): Initializes a Finder. Used by subclasses to initialize the skipOffstage property.

allCandidates → Iterable<Element>: Returns all the Elements that will be considered by this finder.
protected">@protectedread-only
description → String: Describes what the finder is looking for. The description should be a brief English noun phrase describing the finder's pattern.
read-only
first → Finder: Returns a variant of this finder that only matches the first element matched by this finder.
read-only
hashCode → int: The hash code for this object.
read-onlyinherited
last → Finder: Returns a variant of this finder that only matches the last element matched by this finder.
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited
skipOffstage → bool: Whether this finder skips nodes that are offstage.
final

apply(Iterable<Element> candidates) → Iterable<Element>: Returns all the elements in the given list that match this finder's pattern.
at(int index) → Finder: Returns a variant of this finder that only matches the element at the given index matched by this finder.
evaluate() → Iterable<Element>: Returns the current result. If precache was called and returned true, this will cheaply return the result that was computed then. Otherwise, it creates a new iterable to compute the answer.
hitTestable({Alignment at = Alignment.center}) → Finder: Returns a variant of this finder that only matches elements reachable by a hit test.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
precache() → bool: Attempts to evaluate the finder. Returns whether any elements in the tree matched the finder. If any did, then the result is cached and can be obtained from evaluate.
toString() → String: A string representation of this object.
