Use the correct camera profiles for Android and for iOS

Hello. I am trying to use the camera plugin for two purposes in my app:

1. Allow the user to record a video
2. Process the video alongside recording with some AI models

I tried to use the camera plugin with two controllers.

  CameraController _cameraRecordingController;
  CameraController _cameraImageStreamController;
.
.
.
// initiate controllers
      if (_cameraRecordingController == null ||
          !_cameraRecordingController.value.isInitialized) {
        _cameraRecordingController = CameraController(
          CameraBloc.cameras[0],
          ResolutionPreset.high,
          enableAudio: false,
        );
        await _cameraRecordingController.initialize();
        await _cameraRecordingController.prepareForVideoRecording();
      }

      if (_cameraImageStreamController == null ||
          !_cameraImageStreamController.value.isInitialized) {
        _cameraImageStreamController = CameraController(
          CameraBloc.cameras[0],
          ResolutionPreset.medium,
          enableAudio: false,
        );
        await _cameraImageStreamController.initialize();
      }
.
.
.
// start recording and imagestream one -by-one
        await _cameraRecordingController.startVideoRecording(event.filePath);
        await _cameraImageStreamController.startImageStream((img) {
          // Do image processing here
        });
.
.
.
.
// finally stop the controllers
        if (_cameraImageStreamController.value.isInitialized)
          await _cameraImageStreamController.stopImageStream();

        if (_cameraRecordingController.value.isInitialized)
          await _cameraRecordingController.stopVideoRecording();

The two controllers are for recording and imagestream respectively.
Do you think this is the right approach of using this plugin for my use-case (I was getting some weird behavior when doing this ex. the camerapreview was hung on a single frame many times)? Is there a better way of doing this (even if not using this plugin)?

In your example, you are hardcoding
bool hasFlash = false;

Is there a better way to determine which camera has a flash than hardcode it to the rear camera?

can I use your camera package on Windows Mac Linux web

Hi,
As the title suggests, I tried to use the flash functionality on three phones but only two works. It works on Samsung Galaxy J2 (Android 6.0.1) Prime and Xiaomi Mi A2 (Android 10), but doesn't work on Samsung Galaxy S10 (Android 10). There is no error on the log too. Does someone have the same issue and found a fix?

Hello, I was using the zoom feature and it is working fine for the camera preview but pictures which are taken after zoom do not zoom and appear as the original picture without zoom.

Seldom crash on iOS, but it does occur now and again. here is the error log:

flutter version

[✓] Flutter (Channel master, 1.26.0-2.0.pre.86, on Mac OS X 10.15.7 19H114 darwin-x64, locale zh-Hans-CN)

Current Behavior
On Android, when autofocus is enabled (the default behavior), a photo is not actually taken until the camera focuses. In other words, the user might press the "Take Photo" button while moving the camera around, and the plugin will wait indefinitely until the user stops moving the camera, and then it will take the photo. As a result, the camera might snap a photo of something entirely different than what it was pointed at when the user tried to take a photo.

Expected Behavior
The camera should immediately take a photo when takePicture is called, even if the camera has not gotten a chance to focus.

Hi! I'm student and I'm developing an android + iOS app in my final university project.

I use this package to get user's heart rate, so I need to use the camera flash. On Android devices, it works perfectly; but on iOS, the flash never activates. I'm doing it like this:
await _cameraController.setFlashMode(FlashMode.torch);

Is it wrong or is there other way to turn on the flash? I've tried to use a couple of packages at the same time, but it says that the camera is already being used.

Thank you very much! I'm looking forward to your responses. Greetings from Spain!

We are grateful to you for adding things that this library flutter team didn't care about. I and my team will let you know if there is an error or a performance issue for the library to improve.

Thank you ! Best regards

I am getting this error for Android 12 OS device.. Let me know once this issue is fixed...

I don't receive an error but visibly the torch mode is not working when setting on the controller. Is this supposed to be implemented?

This is the Minimal Viable Example:

import 'package:flutter/material.dart';
import 'package:flutter_better_camera/camera.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          child: Text('Navigate'),
          onPressed: () {
            Navigator.of(context).push(
              MaterialPageRoute(
                builder: (context) => Camera(),
              ),
            );
          },
        ),
      ),
    );
  }
}

class Camera extends StatefulWidget {
  @override
  _CameraState createState() => _CameraState();
}

class _CameraState extends State<Camera> {
  CameraController _controller;

  @override
  void initState() {
    super.initState();
    _init();
  }

  Future<void> _init() async {
    final _cameras = await availableCameras();
    _controller = CameraController(_cameras[0], ResolutionPreset.high);
    await _controller.initialize();
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: _controller == null ? Container() : CameraPreview(_controller),
    );
  }
}

Steps to reproduce:

1. Run the program
2. Click on the center of the navigate button at the center of the screen
3. Deny both permissions
4. Press back button
5. Click on navigate button again

Hi,
Can you add the exposure compensation function?
I saw the complete code on a pull request of flutter "camera" plugin.
So you just need to copy/paste the code.
I already did it with standard flutter camera, but I think I'll do it again using this better_camera as starting point (so I could have more features).

But after that, I'd like to ask you if you can implement a tap to exposure function (like tap to focus but for exposure) that works with exposure compensation mentioned before.

In this way I can tap on dark areas of my picture to expose there, and then compensate with +2 for example.

Thank you in advance.

Really hard to debug this as it doesn't happen on Android obviously but on iOS 13.x & iOS 14 with Xcode 11.7 the following hard app crash occurs.

How to stream camera and preview Camera stream is you have any idea please tell me

Android 6.0

W/LegacyRequestMapper(12202): convertRequestMetadata - control.awbRegions setting is not supported, ignoring value
W/LegacyRequestMapper(12202): Only received metering rectangles with weight 0.
W/LegacyRequestMapper(12202): Only received metering rectangles with weight 0.

Hi, when I set some zoom, the preview is OK and is taking pictures, however if the flash is ON, the image is taken but with zoom 1.
If the flash mode is off it works as expected.

I have tried after set flash mode to set the zoom again in case set flash mode resets the zoom, but it looks like the zoom never changes, just images with flash has zoom 1, no matter what zoom I have set.
I can experience this with alwaysFlash and torch mode, when use autoFlash it hangs for a few seconds until the image is taken and then is again without zoom.

Sometimes it hangs for longer and need to kill the app and start it again to work the camera correct.

This is happening on android only (Pixel 3a XL, Samsung A52016 and Redmi 7)

Thanks in advance!

The lockCaptureOrientation method will come to the package any time soon?

I'm trying to lock the camera in portrait mode, my app is already locked on portrait mode, but the camera just ignore that and change his orientation if I turn the phone a bit to the left or right.

By the way, great work with the package, was the only one that solved a problem with taking photos with the main back camera.

hi, nice work! i would like to keep flash always on. Currently it starts and then stops with camerapreview,

I have a problem when turn on/off the flash.
I am using flutter_better_camera: 1.0.2+1

Here is code using in my app:

//Turn off
controller.setFlashMode(FlashMode.off);

//Turn on
controller.setFlashMode(FlashMode.torch);

This code not work on iOS device. But work fine on Android device.

I was try catch but don't have any exception.
Pls help me check it. Thank in advance

Hi, with version 1.0.1 , 1.0.2 and 1.0.2+1
when I try to init the camera it crashes the app on iOS.
This is somehow related to Flutter version 3.0.5, with Flutter 2.10.4 version 1.0.1 worked with no problem.

Thanks in advance!

Hi there,

I was wondering if it's possible to take multiple photos without actually leaving the camera screen?

I'm working on an app where the user may want to take multiple photos at once (similar to iOS burst mode).

Thanks!

Hi thanks for this great plugin.
I have an issue on iPads only.
When I try to initialise the camera it stops at await availableCameras();
Has anyone seen such problem?

Thanks in advance!

Enable flutter api to take Burst images

setAutoFocus on iOS does not seem to be implemented. This should at least be documented?

flutter: Caught error: MissingPluginException(No implementation found for method setAutoFocus on channel plugins.flutter.io/camera)
