## 1.1.0
**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
## 1.0.3
* Fixes `build.gradle`.

# file_picker
File picker plugin alows you to use a native file explorer to load absolute file path from different types of files.
File picker plugin alows you to use a native file explorer to load absolute file path from different file types.
## Installation
First, add *file_picker* as a dependency in [your pubspec.yaml file](https://flutter.io/platform-plugins/).
```
file_picker: ^1.0.2
file_picker: ^1.1.0
```
## Android
Add `<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />` to your app `AndroidManifest.xml` file.
Add `<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>` to your app `AndroidManifest.xml` file.
## iOS
Since we are using *image_picker* as a dependency from this plugin to load paths from gallery and camera, we need the following keys to your _Info.plist_ file, located in `<project root>/ios/Runner/Info.plist`:

* `NSPhotoLibraryUsageDescription` - describe why your app needs permission for the photo library. This is called _Privacy - Photo Library Usage Description_ in the visual editor.
* `NSCameraUsageDescription` - describe why your app needs access to the camera. This is called _Privacy - Camera Usage Description_ in the visual editor.
* `NSMicrophoneUsageDescription` - describe why your app needs access to the microphone, if you intend to record videos. This is called _Privacy - Microphone Usage Description_ in the visual editor.
* `UIBackgroundModes` with the `fetch` and `remote-notifications` keys - describe why your app needs to access background taks, such downloading files (from cloud services) when not cached to locate path. This is called _Required background modes_, with the keys _App download content from network_ and _App downloads content in response to push notifications_ respectively in the visual editor (since both methods aren't actually overriden, not adding this property/keys may only display a warning, but shouldn't prevent its correct usage).
## To-do
## Currently supported features
* [X] Load paths from **cloud files** (GDrive, Dropbox, iCloud)
* [X] Load path from **PDF**
* [X] Load path from **gallery**
* [X] Load path from **camera**
* [X] Load path from **video**
* [X] Load path from **any** type of file (without filtering)
* [ ] Load path from a **custom format**
* [X] Load path from a **custom format** by providing a file extension (pdf, svg, zip, etc.)

# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# To add custom fonts to your plugin package, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
