An image (also with videos) picker based on Instagram picker UI. It is using the powerful [flutter_wechat_assets_picker](https://pub.dev/packages/wechat_assets_picker)

## 🚀 Features
- ✅ Instagram layout
- Scroll behaviors, animation
- Preview, select, unselect action logic
- ✅ Image and Video ([but not video processing](#video)) support
- ✅ Theme and language customization
- ✅ Multiple assets pick (with maximum limit)
- ✅ Single asset pick mode
- ✅ Restore state of picker after pop
- ✅ Select aspect ratios to crop all assets with (default to 1:1 & 4:5)
- ✅ Crop all image assets at once and receive a stream with a progress value
- ✅ Prepend or append a custom item in the assets list
- ✅ Add custom action buttons

context,
pickerConfig: InstaAssetPickerConfig(
title: 'Select assets',
),
maxAssets: 10,
onCompleted: (Stream stream) {
// TODO : handle crop stream result
// i.e : display it using a StreamBuilder
// - in the same page (closeOnComplete=true)
// - send it to another page (closeOnComplete=false)
// or use `stream.listen` to handle the data manually in your state manager
// - ...
},

### Picker configuration
Please follow `flutter_wechat_assets_picker` documentation : [AssetPickerConfig](https://pub.dev/packages/wechat_assets_picker#usage-)
### Localizations
Please follow `flutter_wechat_assets_picker` documentation : [Localizations](https://pub.dev/packages/wechat_assets_picker#localizations)
### Theme customization
Most of the components of the picker can be customized using theme.
```dart
// set picker theme based on app theme primary color
final theme = InstaAssetPicker.themeData(Theme.of(context).primaryColor);
InstaAssetPicker.pickAssets(
context,
pickerConfig: InstaAssetPickerConfig(
pickerTheme: theme.copyWith(
canvasColor: Colors.black, // body background color
splashColor: Color.grey, // ontap splash color
colorScheme: theme.colorScheme.copyWith(
background: Colors.black87, // albums list background color
),
appBarTheme: theme.appBarTheme.copyWith(
backgroundColor: Colors.black, // app bar background color
titleTextStyle: Theme.of(context)
.appBarTheme
.titleTextStyle
?.copyWith(color: Colors.white), // change app bar title text style to be like app theme
),
// edit `confirm` button style
textButtonTheme: TextButtonThemeData(
style: TextButton.styleFrom(
foregroundColor: Colors.blue,
disabledForegroundColor: Colors.red,
),
),
),
),
onCompleted: (_) {},
);
```
### Crop customization
You can set the list of crop aspect ratios available.
You can also set the preferred size, for the cropped assets.
```dart
InstaAssetPicker.pickAssets(
context,
pickerConfig: InstaAssetPickerConfig(
cropDelegate: InstaAssetCropDelegate(
// allows you to set the preferred size used when cropping the asset.
// the final size will depends on the scale used when cropping.
preferredSize: 1080,
cropRatios: [
// - allow you to set the list of aspect ratios selectable,
// the default values are [1/1, 4/5] like instagram.
// - if you want to disable cropping, you can set only one parameter,
// in this case, the "crop" button will not be displayed (#10).
// - if the value of cropRatios is different than the default value,
// the "crop" button will display the selected ratio value (i.e.: 1:1)
// instead of unfold arrows.
]),
),
onCompleted: (_) {},
);
```
### Camera
Many people requested the ability to take picture from the picker.
The main aspect of this package is selection and uniform crop selection.
Consequently, camera-related operations have no place in this package.
However, since version `2.0.0`, it is now possible to trigger this action using either `specialItemBuilder` and/or `actionsBuilder`.
The ability to take a photo from the camera must be handled on your side, but the picker is now able to refresh the list and select the new photo.
New [examples](https://github.com/LeGoffMael/insta_assets_picker/tree/main/example/lib/pages/camera) have been written to show how to manage this process with the [camera](https://pub.dev/packages/camera) or [wechat_camera_picker](https://pub.dev/packages/wechat_camera_picker) package.
### Video
Video are now supported on version `3.0.0`. You can pick a video asset and select the crop area directly in the picker.
However, as video processing is a heavy operation it is not handled by this package.
Which means you must handle it yourself. If you want to preview the video result, you can use the `InstaAssetCropTransform` which will transform the Image or VideoPlayer to fit the selected crop area.
The example app has been updated to support videos (+ camera recording) and shows [how to process the video](https://github.com/LeGoffMael/insta_assets_picker/tree/main/example/lib/post_provider.dart#L84) using [ffmpeg_kit_flutter](https://pub.dev/packages/ffmpeg_kit_flutter).
