read-onlyoverride
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited

Methods

booleanValue() → bool
Returns this value as a bool if the type matches, otherwise returns false.
codecValue() → dynamic
Returns a raw platform representation of the value.
doubleValue() → double
Returns this value as a double if the value is numeric, otherwise returns 0.
get(int index) → LDValue
Retrieves an array element by index.
getFor(String key) → LDValue
Retrieves an object element by index.
getType() → LDValueType
Returns the type of this value.
intValue() → int
Returns this value as an int if the value is numeric, otherwise returns 0.
keys() → Iterable<String>
Enumerates the property names in an object, returns an empty iterable for all other types.
noSuchMethod(Invocation invocation) → dynamic

inherited
numValue() → num
Returns this value as a num if the value is numeric, otherwise returns 0.
size() → int

inherited
values() → Iterable<LDValue>
Enumerates the property values in an array or object, returns an empty iterable for all other types.

Operators

operator ==(Object other) → bool
The equality operator.
override
