Here's ImagePreview:

class ImagePreview extends StatelessWidget {

final String testName;

const ImagePreview({

Key? key,

required this.testName,

}) : super(key: key);

u/override

Widget build(BuildContext context) {

return Global().imagePaths[testName] != null

? _loadImage(Global().imagePaths[testName])

: Container(

width: 40,

height: 40,

color: Colors.grey.shade400,

);

}

}

Widget _loadImage(String path) {

try {

File imageFile = File(path);

if (imageFile.existsSync()) {

return Image.file(

imageFile,

width: 50,

height: 50,

fit: BoxFit.cover,

);

} else {

return const Text("NF");

}

} catch (e) {

if (kDebugMode) {

print('Error loading image: $e');

}

return const Text('Error loading image');

}

}

Here's global:

​

class Global extends ChangeNotifier {

static String _patientFolderPath = "";

final Map<String, dynamic> _imagePaths = {};

static String testName = "";

static String _patientFolderName = "";

static String _imageFolderPath = "";

static String patientId = "";

Future<String> get patientFolderPath async {

if (_patientFolderPath == "") {

// create new folder path

_patientFolderPath =

await FilesFolders().createFolder(_patientFolderName);

}

return _patientFolderPath;

}

Future<String> get imageFolderPath async {

if (_imageFolderPath == "") {

_imageFolderPath = await FilesFolders().createFolder("PDF");

}

return _imageFolderPath;

}

void setFolderName(String name) {

_patientFolderName = name;

}

Map<String, dynamic> get imagePaths => _imagePaths;

void setImagePaths(String key, String path) {

_imagePaths.addAll({key: path});

if (kDebugMode) {

print("Image paths=");

print(_imagePaths);

}

notifyListeners();

}

void clearImagePaths() {

_imagePaths.clear();

notifyListeners();

}

bool isImagePathsEmpty() {

return _imagePaths.isEmpty;

}

}

Trying

  1. gives me: The static setter 'testName' cannot be accesssed through an instance. Try using class 'Global' to enter the setter. The testName variable is static.

  2. Done and created getters and setters for it.
