# selectFrom method

override

Performs a Logic `index`

based selection on an List of Logic
named `busList`

.

Using the Logic `index`

on which selectFrom is performed on and
a List of Logic named `busList`

for `index`

based selection, we can
select any valid element of type Logic within the `logicList`

using
the `index`

of Logic type.

Alternatively we can approach this with `busList.selectIndex(index)`

Example:

```
// ordering matches closer to array indexing with `0` index-based.
selected <= index.selectFrom(busList);
```

## Implementation

```
@override
Logic selectFrom(List<Logic> busList, {Logic? defaultValue}) =>
packed.selectFrom(busList, defaultValue: defaultValue);
```
