Notifies of data at the queried table.


<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
supabase
  .from('countries')
  .stream()
  .execute();
```


</TabsPanel>

</Tabs>





## Notes

- `stream()` will emit the initial data as well as any further change on the database as `Stream` of `List<Map<String, dynamic>>` by combining Postgrest and Realtime.










## Examples

### Listening to a specific table



<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
supabase
  .from('countries')
  .stream()
  .execute();
```


</TabsPanel>

</Tabs>

### Listening to a specific rows within a table

You can listen to individual rows using the format `{table}:{col}=eq.{val}` - where `{col}` is the column name, and `{val}` is the value which you want to match.
This syntax is the as how you can filter data in Realtime


<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
supabase
  .from('countries:id=eq.120')
  .stream()
  .execute();
```


</TabsPanel>

</Tabs>

### With `order()`



<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
supabase
  .from('countries')
  .stream()
  .order('name', ascending: false)
  .execute();
```


</TabsPanel>

</Tabs>

### With `limit()`



<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
supabase
  .from('countries')
  .stream()
  .order('name', ascending: false)
  .limit(10)
  .execute();
```


</TabsPanel>
