FitGridColumnFilter class

One column's filter, as data.

Deliberately a value rather than a closure: it can be shown back to the user in the filter panel, saved with the rest of the grid's state, and sent to a server as JSON — none of which a bool Function(T) can do.

Properties

hashCode → int

The hash code for this object.

no setter, override

operator → FitGridFilterOperator

final

no setter, inherited

The operand: a String, a num or a DateTime, by the column's kind.

Methods

matches(String text, Object? typed) → bool

Tests a cell. text is the column's text for the row; typed is the value its filter spec extracts, for number and date columns.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, Object?>

A JSON-friendly map. Numbers stay numbers; a date becomes {"date": "<ISO-8601>"}, so it cannot be mistaken for a string operand on the way back in.

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
