Scanny - Only for Andorid

A document scanner plugin for Android. This plugin is a Document scanner which can be used for free. Just add the plugin into your project and start using it

Getting Started

This plugin is built for android for now. Scan the document and you would get the image of the document

Add the dependency

    dependencies:
        scanny: ^0.1.0

Install the plugin

flutter pub get

Usage

Instantiate Scanny plugin and pass it to any custom widget

For instance

Instantiate the Scanny plugin 
class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState(new Scanny());
}

Scanny provides you with 2 methods

  1. askPermissions - for asking camera and storage permissions
  2. callScanner - This will instiate the scanner activity of the android

askPermissions is straight forward to use

For instance

      Future<void> askPermissions() async {
        await scanny.askPermissions;
      }

callScanner usage

Use this method to initiate the scanning activity 

 dynamic _imageBytes;
 Future<void> scanDocument() async {
    try {
      //ask permissions if permissions are not granted yet
      await askPermissions();
      //call the scanner
       scanny.callScanner;
       //listen to the results of activity
       scanny.getImageBytes.listen((imageBytes){
         setState(() {
           _imageBytes = imageBytes;
         });
       });
    }
    catch(error) {
      print(error);
    }
  }

Results -

We get the image results in the form of imageBytes so we store them in dynamic datatype for the sake of simplicity

 scanny.getImageBytes.listen((imageBytes){
         setState(() {
           _imageBytes = imageBytes;
         });
       });

Displaying the results in Flutter

Displaying of the returned images can be done using Image.memory widget.

For instance

Image.memory(_imageBytes)
