i have a problem with native-base and react-native-router-flux.
The Drawer wont open when i click on the menu in the top bar (on snack you see just a questionmark instead of the menu icon) and i don't know whats wrong with the code.
Could anyone help me with this or have a better example then the on on github?
Code is on Snack:
https://snack.expo.io/#snak3/test-with-native-base-drawer-and-native-router-flux
ok, i found the solution.
Look at the working Snack Example:
https://snack.expo.io/#snak3/test-with-native-base-drawer-and-native-router-flux
But i have to say that the documentation for react-native-router-flux is the worst i ever saw. Please if your read this here provide more examples and maybe with less stuff around and more comments!

You could use this library:
https://github.com/react-native-material-design/react-native-material-design
I think it can solve your problem
This RN starter has an example as well:
https://github.com/infinitered/ignite
You should not implement it from scratch yourself but instead you can use a starter project like this. If you want these animations on the drawer icon you can also check the Airbnb's Lottie.

At the time, this one worked for me (0.63.4). The others I found were from previous versions (0.45) and required a lot of adjustments regarding newer version implementations. No other extra files are needed except these ones after creating a unmanaged blank project:
App.js
LoginScreen.js
HeaderComponent.js
FirstScreen.js
SecondScreen.js
I am using react-native-camera to build a barcode scanner for Android and iOS both.
I am able to scan the barcode in iOS but the issue is there is no visual for the scanning boundary. And I want the whole screen to be able to scan the bar code not just the middle of the screen.
Is there any way around it?
If there is some other library that would also work for me.
Well it took me all day but I finally found a library that worked. If anyone finds their way here and is looking for a barcode scanner for react native that works on android...I am here to help.

1st if you do not have rnpm get it...it is very helpful!(npm install -g rnpm)(https://github.com/rnpm/rnpm)
then run these commands in your project file:
npm install --save react-native-barcodescanner
rnpm link react-native-barcodescanner
at this point I synced gradle and reran the app from android studios...not sure if it is needed(also sometimes rnpm link forgets a new line character...if you have an error message about the word include it is because this...just find it in your setting.gradle file add a new line before the word include)
now it is ready to use.
import it:
import BarcodeScanner from 'react-native-barcodescanner';
then use it in your render function's return statment:
<BarcodeScanner
onBarCodeRead={this._BarCodeRead}
style={styles.preview}
torchMode='off'
cameraType='back'
/>
If you need more info check out that link. I hope this helped someone avoid the torture I endured going through library after old library that did not work.
Happy coding! :)
I recommend using React Native Community's React Native Camera. It's quite well maintained and you can simply pass a callback prop to receive the output:
<RNCamera onBarCodeRead={this.handleBarCodeRead}></RNCamera>
Your callback will be invoked when a barcode is detected in the camera's view. From the docs:
Event contains data (the data in the barcode) and type (the type of the barcode detected).
There is a react-native library for scanning QR codes with Highlighting scanning area with animated scan bar that moves up and down.
You can use isShowScanBar prop to show scan bar or either disable by passing false to this prop.
Github Link https://github.com/shifeng1993/react-native-qr-scanner#readme
It's npm is also here https://www.npmjs.com/package/react-native-qr-scanner
It's props are listed here https://www.npmjs.com/package/react-native-qr-scanner#qrscanner
Firstly, Install the react-native-camera library as this library is dependent on it.
Just run this command in root directory of your project
npm i react-native-qr-scanner
then run this link command react-native link react-native-camera && react-native-qr-scanner
Import it using :
import {QRscanner} from 'react-native-qr-scanner';
<QRscanner onRead={this.onRead}
cornerBorderColor ='black'
cornerRadius={40}
isRepeatScan = {true}
cornerBorderRadius={40}
cornerColor ='black'
scanBarColor='black'
cornerBorderWidth={10}
cornerBorderLength={60}
hintText="Please Align QRCode"
renderBottomView={this.bottomView} flashMode={this.state.flashMode}
finderY={50}/>
onRead = (res) => {
alert(JSON.stringify(res))
}
It works for both Android and iOS
js.coach is a good place to look for react native plugins

Just found universal code scanner - combines android and ios:
https://www.npmjs.com/package/react-native-barcode-scanner-universal
Tried on Android works just fine.
Expo provides BarCodeScanner component out of the box (preinstalled in managed apps).
It works like a charm, I definitely recommend it.
You can see if BarCodeScanner works with your bar code, try it in snack: https://snack.expo.io/#documentation/barcodescanner-example
