5.1.0 #

• Added a new MemoryFileSystem constructor to use a test clock

5.0.10 #

• Added example

5.0.9 #

• Fix lints for project health

5.0.8 #

• Return Uint8List rather than List

5.0.7 #

• Dart 2 fixes for RecordingProxyMixin and ReplayProxyMixin.

5.0.6 #

• Dart 2 fixes for RecordingFile.open()

5.0.5 #

• Dart 2 fixes

5.0.4 #

• Update SDK constraint to 2.0.0-dev.67.0, remove workaround in recording_proxy_mixin.dart.
• Fix usage within Dart 2 runtime mode in Dart 2.0.0-dev.61.0 and later.
• Relax constraints on package:test

5.0.3 #

• Update package:test dependency to 1.0

5.0.2 #

• Declare compatibility with Dart 2 stable

5.0.1 #

• Remove upper case constants
• Update SDK constraint to 2.0.0-dev.54.0.

5.0.0 #

• Moved testing library into a dedicated package:file_testing so that libraries don't need to take on a transitive dependency on package:test in order to use package:file.

4.0.1 #

• General library cleanup
• Add style support in MemoryFileSystem, so that callers can choose to have a memory file system with windows-like paths. [#68] (https://github.com/google/file.dart/issues/68)

4.0.0 #

• Change method signature for RecordingRandomAccessFile._close to return a Future<void> instead of Future<RandomAccessFile>. This follows a change in dart:io, Dart SDK 2.0.0-dev.40.

3.0.0 #

• Import dart:io unconditionally. More recent Dart SDK revisions allow dart:io to be imported in a browser context, though if methods are actually invoked, they will fail. This matches well with package:file, where users can use the memory library and get in-memory implementations of the dart:io interfaces.
• Bump minimum Dart SDK to 1.24.0

2.3.7 #

• Fix Dart 2 error.

2.3.6 #

• Relax sdk upper bound constraint to '<2.0.0' to allow 'edge' dart sdk use.

2.3.5 #

• Fix internal use of a cast which fails on Dart 2.0 .

2.3.4 #

• Bumped maximum Dart SDK version to 2.0.0-dev.infinity

2.3.3 #

• Relaxes version requirements on package:intl

2.3.2 #

• Fixed FileSystem.directory(Uri), FileSystem.file(Uri), and FileSystem.link(Uri) to consult the file system's path context when converting the URI to a file path rather than using Uri.toFilePath().

2.3.1 #

• Fixed MemoryFileSystem to make File.writeAs...() update the last modified time of the file.

2.3.0 #

• Added the following convenience methods in Directory:
  • Directory.childDirectory(String basename)
  • Directory.childFile(String basename)
  • Directory.childLink(String basename)

2.2.0 #

• Added ErrorCodes class, which holds errno values.

2.1.0 #

• Add support for new dart:io API methods added in Dart SDK 1.23

2.0.1 #

• Minor doc updates

2.0.0 #

• Improved toString implementations in file system entity classes
• Added ForwardingFileSystem and associated forwarding classes to the main file library
• Removed FileSystem.pathSeparator, and added a more comprehensive FileSystem.path property
• Added FileSystemEntity.basename and FileSystemEntity.dirname
• Added the record_replay library
• Added the testing library

1.0.1 #

• Added FileSystem.systemTempDirectory
• Added the ability to pass Uri and FileSystemEntity types to FileSystem.directory(), FileSystem.file(), and FileSystem.link()
• Added FileSystem.pathSeparator

1.0.0 #

• Unified interface to match dart:io API
• Local file system implementation
• In-memory file system implementation
• Chroot file system implementation
