[cross_file] XFile.fromData on Web is reading the actual file at given path instead of returning the bytes given #163044
Description
Steps to reproduce
XFile.fromData on Web reads the file at given path instead of returning the bytes given to it in constructor. Works as expected on other platforms (I checked macOS only).
- Run the given sample on platform other than web (I used macOS).
- Notice that it shows "Hello World" text in UI which is correct and expected.
- Now run it on web.
- Notice that instead of showing "Hello World", it shows actual contents of the
lib/main.dartfile.
Expected results
It should read "Hello World" as text when calling file.readAsString() on all platforms.
Actual results
I reads the file at given path instead of returning the given bytes on web.
Code sample
Code sample
import 'dart:convert';
import 'package:cross_file/cross_file.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
XFile? file;
@override
void initState() {
super.initState();
file = XFile.fromData(
utf8.encode('Hello World'),
path: 'lib/main.dart',
name: 'main.dart',
length: 11,
mimeType: 'text/plain',
lastModified: DateTime.now(),
);
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(widget.title),
),
body: Center(
child: FutureBuilder(
future: file?.readAsString(),
builder: (context, snapshot) {
if (!snapshot.hasData) {
return const CircularProgressIndicator();
}
return Text(snapshot.data ?? 'No data');
},
),
),
);
}
}
