how can i load files as PlatformFile Type from file path and display them for edit purpose?

[saifonglee]

i have a path like: https://mydomains.com/medias/files/file.pdf or https://mydomains.com/medias/files/image.png
I've used form_builder_file_picker to upload multiple file to my server.

Now i have to load and display them for edit.
I've tried to convert the file as below

List<PlatformFile>? document;
_formatFile() async { PlatformFile? pfile; File file = File(filePath!); var bytes = await file.readAsBytes(); var name = file.path.split('/')[file.path.split('/').length - 1]; var size = bytes.length; pfile = PlatformFile(path: file.path, name: name, size: size); debugPrint(pfile.toString()); setState(() { document!.add(pfile!); }); }

this is the error that occurred:
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PathNotFoundException: Cannot open file, path = 'https://mydomains/medias/files/apfr/299_APFR_BCST-50 manual-V23.pdf' (OS Error: No such file or directory, errno = 2) E/flutter (11435): #0 _checkForErrorResponse (dart:io/common.dart:55:9) E/flutter (11435): #1 _File.open.<anonymous closure> (dart:io/file_impl.dart:381:7)

it's about of this line: var bytes = await file.readAsBytes();

Is there an other way to do that?

problem solved... thanks!
solution
as my file path is an URL, i created this function based on this answer from Stackoverflow: https://stackoverflow.com/a/59589480

getFile(String? filePath) async {
final http.Response responseData = await http.get(Uri.parse(filePath!));
var name = filePath.split('/')[filePath.split('/').length - 1];
Uint8List uint8list = responseData.bodyBytes;
var buffer = uint8list.buffer;
ByteData byteData = ByteData.view(buffer);
var tempDir = await Directory.systemTemp.createTemp();
File file = await File('${tempDir.path}/$name').writeAsBytes(
buffer.asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));
return file;
}

the second function is used to return file as PlatformFile type:

getPlatformFile(String? filePath) async {
PlatformFile? pfile;
File file = await getFile(filePath!); // get file from getFile function
var name = file.path.split('/')[file.path.split('/').length - 1];
var size = await file.length();
pfile = PlatformFile(path: file.path, name: name, size: size);
debugPrint(pfile.toString());
return pfile;
}

you can use this last one to convert your path to a PlatformFile data type.

`PlatformFile? pfile;

pfile = await getPlatformFile(filePath!);`

this is the first solution I've found to solve this. maybe there is a best way to do that.
