# Custom Camera Preview

A component has developed with Flutter

## Purpose

Instead of taking photos of a product and taking them one by one when users need to upload anywhere, they can use custom camera preview to take their photos on the same screen, see them as a list and remove them from the list if they want.

## Instruction

 The Camera Preview as the photo 



 Users can take photos via camera button and save in photo list as below 



If the user would like to delete a photo from the list, the user should use 'delete' button over the image. We deleted dog photo (third photo) from the list (You can compare previous screenshot with photo below)



## Camera Implementation

https://pub.dev/packages/camera

You need import 'package:camera/camera.dart' in the camera preview page. Also, you should initialize your camera controller in initState

```

@override

  void initState() {

    super.initState();

    availableCameras().then((availableCameras) {

      cameras = availableCameras;

      if (cameras.isNotEmpty) {

        setState(() {

          selectedCameraIdx = 0;

        });

        _initCameraController(cameras[selectedCameraIdx]).then((void v) {});

      } else {

        print("No camera available");

      }

    }).catchError((err) {

      print('Error: $err.code\nError Message: $err.message');

    });

  }

```

## Usage

If the camera controller is null or uninitialized, return a loading indicator. If not, return custom camera preview with parameters that you must given a empty list with the type of File and a camera controller

```

if (controller == null || !controller!.value.isInitialized) {

   return const Center(

     child: CircularProgressIndicator(

       color: Colors.red,

     ));

   }

   return CustomCameraPreview(

     imageFiles: _homeController.imageFiles,

     cameraController: controller!,

);

```
