Answer 1

Try this:

static Future<XFile> getImageXFileByUrl(String url) async {
    var file = await DefaultCacheManager().getSingleFile(url);
    XFile result = await XFile(file.path);
    return result;
  }

Answer 2

Anyone can try this code if you also need the mime type or actual file extension,

Need 2 packages path_provider and mime.

import 'package:http/http.dart' show get;

  Future<XFile> getImageXFileByUrl(String url) async {
    Directory tempDir = await getTemporaryDirectory();
    String tempPath = tempDir.path;
    String fileName = "image${DateTime.now().millisecondsSinceEpoch}";
    File fileWrite = new File("$tempPath/$fileName");
    Uri uri = Uri.parse(url);
    final response = await get(uri);
    fileWrite.writeAsBytesSync(response.bodyBytes);
    final mimeType = lookupMimeType("$tempPath/$fileName", headerBytes: [0xFF, 0xD8]);
    final type = mimeType.split("/");
    final file = XFile("$tempPath/$fileName", mimeType: mimeType);
    return file;
  }

headerBytes: [0xFF, 0xD8] was found on the mime readme file.
