toBool function
Converts an object to a bool
.
mirroring the same static method in the ConvertObject, providing alternative easy less code usage options.
- Returns
true
if the object is abool
and equal totrue
. - Returns
true
if the object is aString
and equal to 'yes' or 'true' (case-insensitive). - Returns
true
if the object is anum
,int
, ordouble
and is larger than zero. - Returns
false
for other types or if the object isnull
.
object
The object to be converted to a bool
.
mapKey
(Optional) Specifies the key to extract values from a Map object.
listIndex
(Optional) Specifies the index to extract elements from a List object.
Returns a bool
, with a default value of false
.
Example usage:
final object1 = true;
final bool1 = toBool(object1); // true
final object2 = 'yes';
final bool2 = toBool(object2); // true
final object3 = 10;
final bool3 = toBool(object3); // true
final object4 = false;
final bool4 = toBool(object4); // false
final object5 = 'no';
final bool5 = toBool(object5); // false
final object6 = null;
final bool6 = toBool(object6); // false
Implementation
bool toBool(
dynamic object, {
Object? mapKey,
int? listIndex,
}) =>
ConvertObject.toBool(object, mapKey: mapKey, listIndex: listIndex);
