Examples

Simple example

  FutureListBuilder<Book>(
    url: "https://example.com/get/data",
    httpMethod: HttpMethod.get,
    converter: (json) {
     //Function to convert from json to Book Object.
    },
    itemBuilder: (data) {
     //Function to return card widget for the data Book.
    },
    dataPath: ['data'],  //The data path in the json response body.
    shimmerBuilder: () => ShimmerCard(width: 200, height: 100),
  )

In this example we get data from https://example.com/get/data with Http get method.
and we user the build in ShimmerCard you can read more about it in the docs,
In this example the response body should be

{
  "data": ["item1", "item2"]
}

Full example

In this example we will get a list of locations we will use: location object, shimmer effect and pagination

• The location object class

class Location {
  String textLocation;
  String id;

  Location({
    required this.textLocation,
    required this.id,
  });

  factory Location.fromJson(Map<String, dynamic> json) =>
      Location(
        textLocation: json["text_location"],
        id: json["_id"],
      );
}

• The Location card widget

  Widget LocationCard(Location location) {
  return Container(
    padding: const EdgeInsets.symmetric(horizontal: 12.0, vertical: 8.0),
    margin: const EdgeInsets.symmetric(horizontal: 10.0),
    decoration: BoxDecoration(borderRadius: BorderRadius.circular(50)),
    child: Row(
      children: [
        Text(location.textLocation),
        const SizedBox(width: 8.0),
      ],
    ),
  );
}

• The FutureList widget

  FutureListBuilder<Location>
(
url: "https://example.com/get/locations",
httpMethod: HttpMethod.get,
converter: Location.fromJson,
itemBuilder: LocationCard,
dataPath: ['data'], //The data path in the json response body.
countPath: ['total_count'], //The total count path in the json response body.
shimmerBuilder: () => ShimmerCard(width: 1,height:100,fillWidth: true),
pagination: true,
onError: (errorMessage){
print("Error: $errorMessage");
},
)

In this example the response body should be

{
  "data": ["item1", "item2"],
  "total_count": 20
}
