asBool method
Converts the current object to a boolean value.
Recognized keywords (case-insensitive):
- 'NULL', 'CANCEL', 'CANCELAR', '', '!', '0', 'FALSE', 'NOT', 'NAO', 'NO', 'NOP', 'DISABLED', 'DISABLE', 'OFF', 'DESATIVADO', 'DESATIVAR', 'DESATIVO', 'N', 'X': Returns
false. - '1', 'S', 'TRUE', 'YES', 'YEP', 'SIM', 'ENABLED', 'ENABLE', 'ON', 'Y', 'ATIVO', 'ATIVAR', 'ATIVADO', 'OK', 'C': Returns
true.
If the object doesn't match any of the recognized keywords:
- If
everythingIsTrueistrue, returnstrue. - If
everythingIsTrueisfalse, throws an ArgumentError.
Example usage:
bool result = someObject.asNullableBool(everythingIsTrue: false);
everythingIsTrue: A boolean flag indicating whether to treat all non-null values astrue. If set totrue, any non-null value (except specific keywords) will be consideredtrue. If set tofalse, an exception will be thrown for unrecognized values.
Returns true or false based on the object's representation.
Throws an ArgumentError if the object doesn't represent a valid option and everythingIsTrue is false.
Implementation
bool asBool({bool everythingIsTrue = true}) => asNullableBool(everythingIsTrue: everythingIsTrue) ?? false;
