React-Native-Camera Error when take photo with modified flashMode attribute -


i getting following error when trying take photo flashmode attribute modified:

{ nslocalizeddescription: 'error domain=avfoundationerrordomain code=-11800 "the operation not completed" userinfo={nsunderlyingerror=0x170440210 {error domain=nsosstatuserrordomain code=-16800 "(null)"}, nslocalizedfailurereason=an unknown error occurred (-16800), nslocalizeddescription=the operation not completed}' } } 2017-09-12 00:08:29.907053-0300 gimenesapp[1936:765074] { [error: error domain=avfoundationerrordomain code=-11800 "the operation not completed" userinfo={nsunderlyingerror=0x170440210 {error domain=nsosstatuserrordomain code=-16800 "(null)"}, nslocalizedfailurereason=an unknown error occurred (-16800), nslocalizeddescription=the operation not completed}]

here piece of code using:

<camera     capturetarget={camera.constants.capturetarget.disk}     ref={(cam) => {       this.camera = cam;     }}      flashmode={this.state.flashmode}>     <button onpress={this.takepicture.bind(this)} transparent        <icon name="ios-radio-button-off" />     </button> </camera>

so, solved error removing 2 calls setstate

here take photo method:

  takepicture() {     const options = {};     this.camera.capture({metadata: options})       .then((data) => {         this.setstate({           photo_path: data.path,           is_not_photo_take: false         });       })       .catch(err => {         console.error(err)       });   };

before, setting state twice in takepicture method. moved outside setstate , error gone.

i not know why, now, working.

if have explanation error, please, share us.
