Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
See the getting started guide for information about using Flutter.

file
- chroot
-
A file system that provides a view into another
FileSystemvia a path. - file
-
Core interfaces containing the abstract
FileSysteminterface definition and all associated types used byFileSystem. - local
-
A local file system implementation. This relies on the use of
dart:ioand is thus not suitable for use in the browser. - memory
-
An implementation of
FileSystemthat exists entirely in memory with an internal representation loosely based on the Filesystem Hierarchy Standard. - record_replay
- File systems that work together to record invocations during live operation and then play invocations back in tests.
- testing
-
Matchers (from
package:test) for use in tests that deal with file systems.

intl
- date_symbol_data_custom
- API to allow setting Date/Time formatting in a custom way. [...]
- date_symbol_data_file
- This file should be imported, along with date_format.dart in order to read locale data from files in the file system.
- date_symbol_data_http_request
- This file should be imported, along with date_format.dart in order to read locale data via http requests to a web server..

- message_lookup_by_library
- Message/plural format library with locale support. This can have different implementations based on the mechanism for finding the localized versions of messages. This version expects them to be in a library named e.g. 'messages_en_US'. The prefix is set in the "initializeMessages" call, which must be made for a locale before any lookups can be done. [...]
