Describes what the finder is looking for. The description should be
a brief English noun phrase describing the finder's pattern.

- hashCode → int
-
The hash code for this object. [...]
read-only, inherited
- last → Finder

Methods
-
apply(
Iterable< Element> candidates) → Iterable<Element> -
Returns all the elements in the given list that match this
finder's pattern. [...]
override
-
at(
int index) → Finder -
Returns a variant of this finder that only matches the element at the
given index matched by this finder.
inherited
-
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. [...]
inherited
-
filter(
Iterable< Element> parentCandidates) → Iterable<Element> - Return another Iterable when given an Iterable of candidates from a parent Finder. [...]
-
hitTestable(
{Alignment at = Alignment.center}) → Finder -
Returns a variant of this finder that only matches elements reachable by
a hit test. [...]
inherited
-
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. [...]
inherited
-
toString(
) → String -
A string representation of this object. [...]
inherited
