Where class - query library

Constructors

Where(String evaluatedField, {dynamic value, Compare? compare, bool? isRequired}): A condition that evaluates to true in the Provider should return Model.
const
Where.exact(String evaluatedField, dynamic value, {bool isRequired = true}): A condition written with brevity. required defaults true.
factory

compare → Compare: The kind of comparison of the evaluatedField to the value. Defaults to Compare.equals. It is the responsibility of the Provider to ignore or interpret the requested comparison.
final
conditions → List<WhereCondition>?: Nested conditions. Leave unchanged for WhereConditions that do not nest.
finalinherited
evaluatedField → String: The Dart name of the field. For example, myField when querying final String myField.
final
hashCode → int: The hash code for this object.
no setterinherited
isRequired → bool: Whether the condition(s) must evaluate to true. Defaults true.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
value → dynamic: The value to compare on the evaluatedField.

contains(dynamic value) → Where
doesNotContain(dynamic value) → Where
isBetween(dynamic value1, dynamic value2) → Where
isExactly(dynamic value) → Where
isGreaterThan(dynamic value) → Where
isGreaterThanOrEqualTo(dynamic value) → Where
isLessThan(dynamic value) → Where
isLessThanOrEqualTo(dynamic value) → Where
isNot(dynamic value) → Where
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>: inherited
toString() → String: A string representation of this object.

byField(String fieldName, List<WhereCondition>? conditions) → List<WhereCondition>: Recursively find conditions that evaluate a specific field. A field is a member on a model, such as myUserId in final String myUserId. If the use case for the field only requires one result, say id or primaryKey, firstByField may be more useful.
firstByField(String fieldName, List<WhereCondition>? conditions) → WhereCondition?: Find the first occurrance of a condition that evaluates a specific field For all conditions, use byField.
