Flutter adding multiple network images on a pdf - flutter

Question

I'm trying to find how could i can load network image in my Pdf. I have a list of details including an image urls. and i want to create the same list in a pdf with multiple pages.
So, i used pdf plugin to create the pages. All the details where loaded except the images. since the images should be downloaded from the server. The pdf pages are created with special widget elements (as like the flutter elements, but call with a prefix) and there is no FutureBuilder to manage the await functions.
Could anybody please help. I really stuck on this.
generatePdf(List<BhaiModel> bhaiList) async {
itemCount = 0;
List<BhaiModel> pageItems = [];
for (int i = 0; i < bhaiList.length; i++) {
if ((i + 1) % 5 == 0) {
pageItems.add(bhaiList[i]);
createPage(pageItems);
pageItems = [];
} else {
pageItems.add(bhaiList[i]);
if (i + 1 == bhaiList.length) {
createPage(pageItems);
}
}
}
final output = await getApplicationDocumentsDirectory();
final file = File("${output.path}/sample.pdf");
await file
.writeAsBytes(await pdf.save())
.then((value) => print("pdf saved"));
OpenFile.open("${output.path}/sample.pdf");
print(output.path);
}
createPage(List<BhaiModel> pageItems) async {
pdf.addPage(pw.Page(
pageFormat: PdfPageFormat.a4,
margin: const pw.EdgeInsets.all(30),
build: (pw.Context context) => pw.Column(
mainAxisAlignment: pageItems.length == 5
? pw.MainAxisAlignment.spaceEvenly
: pw.MainAxisAlignment.start,
children: pageItems.map((e) => customBhaiPdfItem(e)).toList())));
}
pw.Row customBhaiPdfItem(BhaiModel bhai) {
itemCount++;
final netImage = await networkImage(bhai.photo_url);
//THIS MAKE THE FUNCTION ASYNC
return pw.Row(children: [
pw.Container(
