Conditional class
Conditionals can be used to evaluate a set of values and return a bool based on the conditional criteria.
Constructors
-
Conditional({List<
Conditional> ? conditions, EvaluationMode mode = EvaluationMode.and, Map<String, dynamic> ? values}) -
Constructs the conditional. The mode defaults to EvaluationMode.and
and may not be
null.
Properties
-
conditions
→ List<
Conditional> ? -
The sub-conditions to evaluate as the criteria.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- mode → EvaluationMode
-
The mode to use when evaluating the criteria.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
values
→ Map<
String, dynamic> ? -
The key value pairs of values to evaluate against.
final
Methods
-
evaluate(
dynamic actual) → bool -
Evaluats the conditional to return a bool based on the criteria and the
given values. The given values must be a Map or a Map-like object
that implements the
[]operator or else an error will be thrown. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> - Encodes the inner representation of this model to a json compatible map.
-
toString(
) → String -
Returns the string encoded JSON representation for this class. This will
remove all null values and empty collections from the returned string.

Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
fromDynamic(
dynamic map) → Conditional -
Creates a new Conditional from a Map-like dynamic value. The
mapmust be a Map or a Map-like object that supports the[String]operator. -
maybeFromDynamic(
dynamic map) → Conditional? -
Creates a new Conditional from a Map-like dynamic value. The
mapmust be a Map or a Map-like object that supports the[String]operator.
