# built_value_built_list_json_sample
`built_value` sample: parse `JSON` to `BuiltList` dynamically.
## Author: [Petrus Nguyễn Thái Học](https://github.com/hoc081098)
[](https://github.com/hoc081098/test_built_value/actions/workflows/dart.yml)
[](https://pub.dev/packages/lints)
## Use
### Step 1. Define your `Built` classes in `_types`
```dart
/// Register your [Built] classes here.
const List _types = [
MyModel,
MyModelTwo,
];
```
### Step 2. Define your `BuilderFactory`s in `_factories`.
```dart
/// Register your [_BuilderFactory]s here.
final List<_BuilderFactory> _factories = [
_BuilderFactory(
FullType(BuiltMap, [
FullType(String),
FullType(int),
]),
() => MapBuilder(),
),
];
```
### Step 3. Use `deserializeBuiltList` and `deserializeBuiltListNullable` to parse `JSON` to `BuiltList`.
```dart
abstract class MyModel implements Built {
BuiltList get items;
MyModel._();
factory MyModel([void Function(MyModelBuilder) updates]) = _$MyModel;
[...]
}
```
#### `BuiltList deserializeBuiltList(Object json)`
```dart
final json = [
{
'items': [1, 2, null, 3, 3]
},
{
'items': [1, 2, null, 3, 2]
},
{
'items': [1, 2, null, 3]
},
];
BuiltList items = deserializeBuiltList(json);
```
#### `BuiltList deserializeBuiltListNullable(Object json)`.
```dart
final json = [
{
'items': [1, 2, null, 3, 3]
},
{
'items': [1, 2, null, 3, 2]
},
null,
{
'items': [1, 2, null, 3]
},
];
BuiltList items = deserializeBuiltListNullable(json);
```
## Run demo
```shell
dart pub get
dart run ./bin/main.dart
```
