I am using the camera to take a picture and save the picture on phones memory to later send it to AWS. I can take a picture and the path for the picture is there, but I am failing to create a file from the path using:
final imageFile = await File(path);
Why is the file not being created here? I always get 'Image file does not exist' on debug console.
import 'dart:io';
import 'package:camera/camera.dart';
import 'package:flutter/material.dart';
import 'package:path/path.dart';
import 'package:path_provider/path_provider.dart';
class CameraPage extends StatefulWidget {
// 1
final CameraDescription? camera;
// 2
final ValueChanged? didProvideImagePath;
CameraPage({Key? key, this.camera, this.didProvideImagePath})
: super(key: key);
@override
State<StatefulWidget> createState() => _CameraPageState();
}
class _CameraPageState extends State<CameraPage> {
CameraController? _controller;
Future<void>? _initializeControllerFuture;
@override
void initState() {
super.initState();
// 3
_controller = CameraController(widget.camera!, ResolutionPreset.medium);
_initializeControllerFuture = _controller?.initialize();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: FutureBuilder<void>(
future: _initializeControllerFuture,
builder: (context, snapshot) {
// 4
if (snapshot.connectionState == ConnectionState.done) {
return CameraPreview(this._controller!);
} else {
return Center(child: CircularProgressIndicator());
}
},
),
// 5
floatingActionButton: FloatingActionButton(
child: Icon(Icons.camera), onPressed: _takePicture),
);
}
// 6
void _takePicture() async {
try {
await _initializeControllerFuture;
final tmpDirectory = await getTemporaryDirectory();
final filePath = '${DateTime.now().millisecondsSinceEpoch}.jpg';
final path = join(tmpDirectory.path, filePath);
await _controller?.takePicture();
widget.didProvideImagePath!(path);
final imageFile = await File(path);
if (imageFile.existsSync())
print('Image file exists');
else
print('Image file does not exist');
} catch (e) {
print(e);
}
}
// 7
@override
void dispose() {
_controller?.dispose();
super.dispose();
}
}
takePicture method will return taken image as XFile, you can use the XFile path to create a File with taken Image path like below code.
File? imageFile;
XFile? xFile = await _controller?.takePicture();
if (xFile != null) {
imageFile = File(xFile.path);
}
if (imageFile != null && imageFile.existsSync()) {
print('Image file exists');
} else {
print('Image file does not exist');
}
