Question

Answer 1

for ones who do not need to cache the image can use meet_network_image package,

The package basic usage :

                MeetNetworkImage(
                  imageUrl:
                      "https://random.dog/3f62f2c1-e0cb-4077-8cd9-1ca76bfe98d5.jpg",
                  loadingBuilder: (context) => Center(
                        child: CircularProgressIndicator(),
                      ),
                  errorBuilder: (context, e) => Center(
                        child: Text('Error appear!'),
                      ),
                )

In addition, you can do that by yourself with using a FutureBuilder,

We need to get data with http call that way, we need to import http before import you also need to add pubspec.yaml and run the command flutter packages get

import 'package:http/http.dart' as http;

  FutureBuilder(
    // Paste your image URL inside the htt.get method as a parameter
    future: http.get(
        "https://random.dog/3f62f2c1-e0cb-4077-8cd9-1ca76bfe98d5.jpg"),
    builder: (BuildContext context, AsyncSnapshot snapshot) {
      switch (snapshot.connectionState) {
        case ConnectionState.none:
          return Text('Press button to start.');
        case ConnectionState.active:
        case ConnectionState.waiting:
          return CircularProgressIndicator();
        case ConnectionState.done:
          if (snapshot.hasError)
            return Text('Error: ${snapshot.error}');
          // when we get the data from the http call, we give the bodyBytes to Image.memory for showing the image
          return Image.memory(snapshot.data.bodyBytes);
      }
      return null; // unreachable
    },
  );
