NoSuchMethod error

[HinnaRutaba]

I cloned and execute your project on my device and it throws following exception:
I/flutter (23369): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
I/flutter (23369): The following NoSuchMethodError was thrown building FutureBuilder<List>(dirty, state:
I/flutter (23369): _FutureBuilderState<List>#45b6d):
I/flutter (23369): The getter 'length' was called on null.
I/flutter (23369): Receiver: null
I/flutter (23369): Tried calling: length

Can you kindly tell me how to fix that
Thanks and Regards

I get this error:
Exception has occurred.
_TypeError (type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'FutureOr<List>')

Has anyone else had this?

probably BASE_URL = 'http://dummy.restapiexample.com/api/v1' may not be working or sending data to your app

use
Map<String, dynamic> map = json.decode(response.body);
return map['data'];

in place of
return json.decode(response.body);

in rest_api.dart
