Description:

cross file

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:

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

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

final String fileContent = await file.readAsString();
print('Content of the file: $fileContent');

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.
Browser compatibility #

Testing #
This package supports both web and native platforms. Unit tests need to be split
in two separate suites (because native code cannot use dart:html, and web code
cannot use dart:io).
When adding new features, it is likely that tests need to be added for both the
native and web platforms.
Native tests #
Tests for native platforms are located in the x_file_io_test.dart. Tests can
be run with dart test.
Web tests #
Tests for the web platform live in the x_file_html_test.dart. They can be run
with dart test -p chrome.
