Im new at Flutter and im trying to add images taken in my app to a custom folder in the gallery. Its the same as on WhatsApp, if you take a picture in a chat the WhatsApp create a custom folder called WhatsApp Images.
For that, I tried this:
Future<bool> saveFile(String url, String fileName) async {
Directory directory;
try {
if (Platform.isAndroid) {
if (await _requestPermission(Permission.storage)) {
directory = (await getExternalStorageDirectory())!;
String newPath = '';
List<String> folders = directory.path.split('/');
for (int x = 1; x < folders.length; x++) {
String folder = folders[x];
if (folder != 'Android') {
newPath += '/$folder';
} else {
break;
}
}
newPath = '$newPath/OnlaineApp';
directory = Directory(newPath);
} else {
return false;
}
} else {
if (await _requestPermission(Permission.photos)) {
directory = await getTemporaryDirectory();
} else {
return false;
}
}
if (!await directory.exists()) {
await directory.create(recursive: true);
}
if (await directory.exists()) {
File saveFile = File('${directory.path}/$fileName');
await dio.download(url, saveFile.path,
onReceiveProgress: (downloaded, totalSize) {
setState(() {
progress = downloaded / totalSize;
});
});
if (Platform.isIOS) {
await ImageGallerySaver.saveFile(
saveFile.path,
isReturnPathOfIOS: true,
);
}
return true;
}
} catch (e) {
print(e);
}
return false;
}
Future<bool> _requestPermission(Permission permission) async {
if (await permission.isGranted) {
return true;
} else {
var result = await permission.request();
if (result == PermissionStatus.granted) {
return true;
} else {
return false;
}
}
}
downloadFile() async {
setState(() {
loading = true;
});
bool downloaded = await saveFile(
'lib/assets/images/fundo_interno.png',
'OnlaineApp Imagens',
);
if (downloaded) {
print('File downloaded');
} else {
print('Problem downloaded file');
}
setState(() {
loading = false;
});
}
I already add in Android>app>src>main> AndroidManifest.xml these lines of code (for permission):
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
...
android:requestLegacyExternalStorage="true"
The problem I got is: I/flutter ( 5424): FileSystemException: Creation failed, path = '/storage/emulated/0/OnlaineApp' (OS Error: Permission denied, errno = 13)
class AudioRecorder {
static DateTime now = DateTime.now();
static String timestamp = now.toString();
var recorder = FlutterAudioRecorder2("./file_path",
audioFormat: AudioFormat.AAC);
// or var recorder = FlutterAudioRecorder2("file_path.mp3");
startRecording() async {
await recorder.initialized;
await recorder.start(); // <- error here
}
stopRecording() async {
var result = await recorder.stop();
}
}
I can't find a way to fix , mainly because I don't understand what does it means, why it says "cannot find the file" but the file needs to be created? (since it's a recording?)
Few points I noticed are
Please check if its initialised or not in the initstate
await recorder.initialized;
//after initialisation add this
var current = await recorder.current(channel: 0);
//you should get the current status as initialised if its done properly.
then on start recording use
await recorder.start()
Also make sure that the file path is right
Edit
This is the code to init the recorder
_init() async {
try {
bool hasPermission = await FlutterAudioRecorder2.hasPermissions ?? false;
if (hasPermission) {
String customPath = '/flutter_audio_recorder_';
io.Directory appDocDirectory;
// io.Directory appDocDirectory = await getApplicationDocumentsDirectory();
if (io.Platform.isIOS) {
appDocDirectory = await getApplicationDocumentsDirectory();
} else {
appDocDirectory = (await getExternalStorageDirectory())!;
}
// can add extension like ".mp4" ".wav" ".m4a" ".aac"
customPath = appDocDirectory.path + customPath + DateTime.now().millisecondsSinceEpoch.toString();
_recorder = FlutterAudioRecorder2(customPath, audioFormat: AudioFormat.AAC);
await _recorder!.initialized;
// after initialization
var current = await _recorder!.current(channel: 0);
print(current);
// should be "Initialized", if all working fine
} else {
ScaffoldMessenger.of(context).showSnackBar(
SnackBar(content: Text("You must accept permissions")));
}
} catch (e) {
print(e);
}
}

I am trying to create a CSV Controller but I got a syntax error The method 'getExternalStorageDirectory' isn't defined for the type 'CsvController'
Here's the part I have problem in:
static Future<String> _getFilePath(String fileName) async {
Io.Directory appDocumentsDirectory = await getExternalStorageDirectory(); // 1
String appDocumentsPath = appDocumentsDirectory.path; // 2
String filePath = '$appDocumentsPath/$fileName.csv'; // 3
return filePath;
}
Here's also I have an error Undefined name 'General' and this is the below part related:
static Future<Io.File> _saveFile(String fileDataString, {index = 0}) async {
try {
Io.File file = Io.File(await _getFilePath(
"${General.getDate().millisecondsSinceEpoch}" +
(index > 0 ? "($index)" : "")));
if (!file.existsSync()) {
// 1
file.writeAsStringSync(fileDataString); // 2
return file;
} else {
return _saveFile(fileDataString, index: index + 1);
}
} catch (e) {
print(e.toString());
return null;
}
}
and this is the below full code I have:
import 'package:csv/csv.dart';
import 'dart:io' as Io;
import 'package:ext_storage/ext_storage.dart';
class CsvController {
static Future<Io.File> getCsvFromList(List<List<dynamic>> csvDataList) async {
try {
String csvDataString = const ListToCsvConverter().convert(csvDataList);
Io.File csvFile = await _saveFile(csvDataString);
return csvFile;
} catch (e) {
print(e.toString());
return null;
}
}
static Future<Io.File> getCsvFromString(String csvString) async {
try {
Io.File csvFile = await _saveFile(csvString);
return csvFile;
} catch (e) {
print(e.toString());
return null;
}
}
static Future<String> _getFilePath(String fileName) async {
Io.Directory appDocumentsDirectory = await getExternalStorageDirectory(); // 1
String appDocumentsPath = appDocumentsDirectory.path; // 2

return filePath;
}
static Future<Io.File> _saveFile(String fileDataString, {index = 0}) async {
try {
Io.File file = Io.File(await _getFilePath(
"${General.getDate().millisecondsSinceEpoch}" +
(index > 0 ? "($index)" : "")));
if (!file.existsSync()) {
// 1
file.writeAsStringSync(fileDataString); // 2
return file;
} else {
return _saveFile(fileDataString, index: index + 1);
}
} catch (e) {
print(e.toString());
return null;
}
}
}
#Edited
After solved it, I have still have a problem with the General Key word.
I have figured the problem, because I didn't defined the path provider package:
and this is the full code I have:
import 'package:csv/csv.dart';
import 'dart:io' as Io;
import 'package:path_provider/path_provider.dart';
class CsvController {
static Future<Io.File> getCsvFromList(List<List<dynamic>> csvDataList) async {
try {
String csvDataString = const ListToCsvConverter().convert(csvDataList);
Io.File csvFile = await _saveFile(csvDataString);
return csvFile;
} catch (e) {
print(e.toString());
return null;
}
}
static Future<Io.File> getCsvFromString(String csvString) async {
try {
Io.File csvFile = await _saveFile(csvString);
return csvFile;
} catch (e) {
print(e.toString());
return null;
}
}
static Future<String> _getFilePath(String fileName) async {
Io.Directory appDocumentsDirectory = await getExternalStorageDirectory(); // 1
String appDocumentsPath = appDocumentsDirectory.path; // 2
String filePath = '$appDocumentsPath/$fileName.csv'; // 3
return filePath;
}
static Future<Io.File> _saveFile(String fileDataString, {index = 0}) async {
try {
Io.File file = Io.File(await _getFilePath(
"${General.getDate().millisecondsSinceEpoch}" +
(index > 0 ? "($index)" : "")));
if (!file.existsSync()) {
// 1
file.writeAsStringSync(fileDataString); // 2
return file;
} else {
return _saveFile(fileDataString, index: index + 1);
}
} catch (e) {
print(e.toString());
return null;
}
}
}
This is happening as you don't have a import for path provider and the worst thing is it doesn't show suggestion to import.
adding following line at top of class and will fix
import 'package:path_provider/path_provider.dart';
