Storing Captured Images in an Array and Displaying Them on a Separate Page When a Button is Pressed

[NassimCodeDev]

Hello. I want a way to store captured images in an array, and when a button is pressed to display the image, a page opens that shows the captured images.

In this way, you can make your stuff,example-

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter_doc_scanner/flutter_doc_scanner.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  List<dynamic> _scannedDocuments = []; // Store scanned documents

  Future<void> scanDocument() async {
    dynamic scannedDocument;
    try {
      scannedDocument = await FlutterDocScanner().getScanDocuments() ??
          'Unknown platform document';
    } on PlatformException {
      scannedDocument = 'Failed to get scanned document.';
    }

    if (scannedDocument != null && scannedDocument is List) {
      setState(() {
        _scannedDocuments.addAll(scannedDocument); // Add scanned documents to the list
      });
    }
  }

  Future<void> scanDocumentUri() async {
    dynamic scannedDocument;
    try {
      scannedDocument = await FlutterDocScanner().getScanDocumentsUri() ??
          'Unknown platform document';
    } on PlatformException {
      scannedDocument = 'Failed to get scanned document.';
    }

    if (scannedDocument != null) {
      setState(() {
        _scannedDocuments.add(scannedDocument); // Add scanned document URI to the list
      });
    }
  }

  void viewCapturedImages() {
    Navigator.push(
      context,
      MaterialPageRoute(
        builder: (context) => ImagesPage(images: _scannedDocuments),
      ),
    );
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Document Scanner Example'),
        ),
        body: Center(
          child: Column(
            children: [
              _scannedDocuments.isNotEmpty
                  ? Text("Captured Documents: ${_scannedDocuments.length}")
                  : const Text("No Documents Scanned"),
            ],
          ),
        ),
        floatingActionButton: Padding(
          padding: const EdgeInsets.only(bottom: 16.0),
          child: Column(
            mainAxisAlignment: MainAxisAlignment.end,
            children: [
              Padding(
                padding: const EdgeInsets.symmetric(vertical: 8.0),
                child: ElevatedButton(
                  onPressed: scanDocument,
                  child: const Text("Scan Documents"),
                ),
              ),
              Padding(
                padding: const EdgeInsets.symmetric(vertical: 8.0),
                child: ElevatedButton(
                  onPressed: scanDocumentUri,
                  child: const Text("Get Scan Documents URI"),
                ),
              ),
              Padding(
                padding: const EdgeInsets.symmetric(vertical: 8.0),
                child: ElevatedButton(
                  onPressed: viewCapturedImages,
                  child: const Text("View Captured Images"),
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

// Page to display scanned images
class ImagesPage extends StatelessWidget {
  final List<dynamic> images;

  ImagesPage({required this.images});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Captured Images')),
      body: GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 2,
          crossAxisSpacing: 4,
          mainAxisSpacing: 4,
        ),
        itemCount: images.length,
        itemBuilder: (context, index) {
          return Image.memory(images[index]); // Assuming `images` is a list of Uint8List
        },
      ),
    );
  }
}
