import 'package:flutter/material.dart';
import 'package:path/path.dart';
import 'package:photofilters/photofilters.dart';
import 'package:image/image.dart' as imageLib;
import 'package:image_picker/image_picker.dart';

void main() => runApp(new MaterialApp(home: MyApp()));

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

class _MyAppState extends State<MyApp> {
  String fileName;
  List<Filter> filters = presetFiltersList;
  File imageFile;

  Future getImage(context) async {
    imageFile = await ImagePicker.pickImage(source: ImageSource.gallery);
    fileName = basename(imageFile.path);
    var image = imageLib.decodeImage(imageFile.readAsBytesSync());
    image = imageLib.copyResize(image, width: 600);
     Map imagefile = await Navigator.push(
      context,
      new MaterialPageRoute(
        builder: (context) => new PhotoFilterSelector(
              title: Text("Photo Filter Example"),
              image: image,
              filters: presetFiltersList,
              filename: fileName,
              loader: Center(child: CircularProgressIndicator()),
              fit: BoxFit.contain,
            ),
      ),
    );
    if (imagefile != null && imagefile.containsKey('image_filtered')) {
      setState(() {
        imageFile = imagefile['image_filtered'];
      });
      print(imageFile.path);
    }
  }

  @override

      body: Center(
        child: new Container(
          child: imageFile == null
              ? Center(
                  child: new Text('No image selected.'),
                )
              : Image.file(imageFile),
        ),
      ),
      floatingActionButton: new FloatingActionButton(
        onPressed: () => getImage(context),
        tooltip: 'Pick Image',
