Enable flash

[allanwolski]

Good job, I was looking for this.

Is there a way to enable flash?

[victoraugustolls]

I tried using a package for controlling the flash outside:

https://github.com/clovisnicolas/flutter_lamp

The problem is, it reserves the camera, so the preview won't open. So is there anyway to enable flash in this package? @facundomedica

I also tried using this package without success.

In order of priorities I would like to change Firebase MLKit for something else first, but I'm open to PRs.

I like Firebase MLKit and I need it for other things, like scanning the QR-Code from an image.

Same here, and it is really fast compared to other alternatives that I have tried. So if removing firebase causes a decrease in speed, it might not be worth it. On 2 Nov 2018 21:27 -0300, allanwolski notifications@github.com, wrote:

how to use toggle flash?

[douglaswender]

I need it

[douglaswender]

I did, I was using the dependencies in the pub version

[kaifigirdhar]

@douglaswender Can you please elaborate how you resolve this

[douglaswender]

I used dependencies for git. then I realized that he has a new method that is toogleFlash(), I just created a method to change the application state with the icon on and off.

Dependencies:

fast_qr_reader_view:
    git:
      url: git://github.com/facundomedica/fast_qr_reader_view.git

Method:

Future _turnFlash() async {
    controller.toggleFlash();
    controller.startScanning();
    setState(() {
      isOn = !isOn;
    });
  }

[kaifigirdhar]

I am getting this error: [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method toggleFlash on channel fast_qr_reader_view)

[douglaswender]

Did you add the dependencies to pubspec.yalm? If not added add, if added use the flutter pub getcommand.

[facundomedica]

Fixed!

[douglaswender]

Thanks, are you doing null safety update? I'll probably need in next project ☺️

[facundomedica]

@douglaswender I think it's already in. I'm not a 100% sure, but seems like it. I work as a backend engineer, so it's been a while since I used Flutter 😅
