cross_file #

An abstraction to allow working with files across multiple platforms.

Usage #

Import package:cross_file/cross_file.dart, instantiate a XFile using a path or byte array and use its methods and properties to access the file and its metadata.

Example:

import 'package:cross_file/cross_file.dart';

final file = XFile('assets/hello.txt');

print('File information:');
print('- Path: ${file.path}');
print('- Name: ${file.name}');
print('- MIME type: ${file.mimeType}');

final fileContent = await file.readAsString();
print('Content of the file: ${fileContent}');  // e.g. "Moto G (4)"

You will find links to the API docs on the pub page.

Web Limitations #

XFile on the web platform is backed by Blob objects and their URLs.

It seems that Safari hangs when reading Blobs larger than 4GB (your app will stop without returning any data, or throwing an exception).

This package will attempt to throw an Exception before a large file is accessed from Safari (if its size is known beforehand), so that case can be handled programmatically.
