Try this, I hope this helps
selectImagesFromImagePicker() async{
// e.g
final knowSize = await defindSize(fileSelected, 2);
if (double.parse(knowSize.toString()) > 5.0) {
SomeSnackBar("File too large", "Limit is 5 mb below");
} else {
log("$knowSize mb", name: "FILE SIZE");
filesChosen.add(File(x!));
}
}
// Function to know the size of a certain file
defindSize(String? path, int decimals) {
final file = File(path!);
int bytes = file.lengthSync();
log("lengthSync $bytes", name: "FILE SIZE");
double sizeMb = bytes / (1000 * 1000);
// the return is mb default
return sizeMb.toStringAsFixed(decimals);
// below if you wanted to return suffix just uncomment them
// const suffixes = ["b", "kb", "mb", "gb", "tb"];
// var i = (m.log(bytes) / m.log(1024)).floor();
// return ((bytes / m.pow(1024, i)).toStringAsFixed(decimals)) + suffixes[i];
}
