file_picker_platform_interface

• Added acceptLabel to WindowsOptions and DarwinOptions, letting callers set the confirm button text of the file dialog. On Windows it applies to pickFile(), pickFiles(), getDirectoryPath(), and saveFile(); on macOS only to pickFile()/pickFiles() (getDirectoryPath()/saveFile() do not accept DarwinOptions). Has no effect on iOS, Android or Web. #1861

• Added PlatformFile.lengthSync(), a nullable int returning the file's length in bytes as provided by the underlying file picker result, or null when it did not report one. Named to pair with the existing length(), the same way dart:io's File does.

• Added FilePickerPlatform.skipEntitlementsChecks(), a no-op default hook that platform implementations can override. Lets file_picker dispatch through the platform interface instead of importing file_picker_darwin directly, which kept the facade package from being wasm compatible.
• Added DarwinOptions and DarwinAssetRepresentationMode, letting callers request a specific asset representation (current or compatible) for media selected from the iOS photo library, instead of always using the system default (automatic). Restores functionality that was available before the Darwin implementation was rewritten (previously exposed as a way to disable compression), useful to avoid expensive transcoding for large HEVC, HDR, or slow-motion videos.

• Added PlatformFile.extension, restoring the pre-12.0 convenience getter that was dropped during the federated rewrite. Returns the file extension of name without the leading dot, or null if there is none.

Android

• Use MediaStore Opener (which goes through the gallery) instead of default explorer. (Thank you @tmthecoder).

Web

• Add event when canceling the picker. (Thank you @letranloc).

Other

• Updates example app to null safety.

Adds null safety support (#510).

Breaking Changes

• Unifies all platforms (IO, Web and Desktop) in a single plugin (file_picker) that can be used seamlessly across all. Both file_picker_interface and file_picker_web are no longer mantained from now on.
• You'll now have to use FilePicker.platform.pickFiles() and extract the files from FilePickerResult;
• Because platforms are unified and mixing File instances from dart:io and dart:html required stubbing and bloated code, it's no longer available as helper method so you'll have to instanciate a File with the picked paths;

New features

• Simplified usage, now you only need to use FilePicker.platform.pickFiles() with desired parameters which will return a FilePickerResult with a List<PlatformFile> containing the picked data;
• Added classes FilePickerResult and PlatformFile classes with helper getters;
• On Android all picked files are scoped cached which should result in most of files being available. Caching process is only made once, so once done, the picked instance should be the same;
• On iOS picking audio now supports multiple and cloud picks;
• Added parameter withData that allows file data to be immediately available on memory as Uint8List (part of PlatformFile instance). This is particularly helpful on web or if you are going to upload to somehwere else;
• Major refactor with some clean-up and improvements;

Removed

• Single methods such as getFilePath(), getMultiFilePath(), getFile() and getMultiFile() are no longer availble in favor o pickFiles();

Bug fix: Fixes an issue on Android, where other activity would try to call FilePicker's result object when it shouldn't.

Breaking changes

• FileType.CAMERA is no longer available, if you need it, you can use this package along with image_picker.

New features

• You can now pick multiple files by using the getMultiFilePath() method which will return a Map<String,String> with all paths from selected files, where the key matches the file name and the value its path. Optionally, it also supports filtering by file extension, otherwise all files will be selectable. Nevertheless, you should keep using getFilePath() for single path picking.
• You can now use FileType.AUDIO to pick audio files. In iOS this will let you select from your music library. Paths from DRM protected files won't be loaded (see README for more details).
• Adds getFile() utility method that does the same of getFilePath() but returns a File object instead, for the returned path.

Bug fixes and updates

• This package is no longer attached to the image_picker, and because of that, camera permission is also no longer required.
• Fixes an issue where sometimes the InputStream wasn't being properly closed. Also, its exception is now being forward to the plugin caller.
• Fixes an issue where the picker, when canceled, wasn't calling the result callback on the underlying platforms.

Breaking change: Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

Breaking changes

• FileType.PDF was removed since now it can be used along with custom file types by using the FileType.CUSTOM and providing the file extension (e.g. PDF, SVG, ZIP, etc.).
• FileType.CAPTURE is now FileType.CAMERA

New features

• Now it is possible to provide a custom file extension to filter file picking options by using FileType.CUSTOM

Bug fixes and updates

• Fixes file names from cloud on Android. Previously it would always display Document
• Fixes an issue on iOS where an exception was being thrown after canceling and re-opening the picker.
• Fixes an issue where collision could happen with request codes on Android.
• Adds public documentation to file_picker
• Example app updated.
• Updates .gitignore

• Version 1.0 release.
• Adds support for ANY and VIDEO files.
• Fixes an issue where permissions were recursively asked on Android.
• Fixes an issue where some paths from document files couldn't be loaded with Android 8.0.
• Updates README file to match changes.
• General refactor & cleanup.
