Advanced Camera

This is our custom Camera that enabling you to tap focus, zoom, flashlight.

Note: This plugin use android.hardware.Camera, I have tried to migrate it to android.hardware.Camera2 in development branch, but with lack of understandings I found out so many inconsistency and find it kinda waste of time since Android is developing their new camera CameraX. So until CameraX has released its stable version, I think I will still use this.

There's still so much feature that I haven't include such as video recording, auto white balance, etc.

And please note that Flutter have their own camera plugin, but they haven't include focus and flashlight feature there.

Installation

First, add adv_camera as a dependency in your pubspec.yaml file.

iOS

Add two rows to the ios/Runner/Info.plist:

one with the key Privacy - Camera Usage Description and a usage description.
and one with the key Privacy - Microphone Usage Description and a usage description.

Or in text format add the key:

<key>NSCameraUsageDescription</key>  
<string>Can I use the camera please?</string>  
<key>NSMicrophoneUsageDescription</key>  
<string>Can I use the mic please?</string>

Android

For Android's permission, you have to configure it yourself (using Dexter, etc.), or you can manually turn on its permission at setting.

This plugin is made to support my other plugin adv_image_picker, you can see that its permission is handled there.
