How to change the progress_dialog package to the sn_progress_dialog package? I'm trying to make a file downloader app with a progress dialog, but the progress_dialog package is not null safety.
Future _downloadAndSaveFileToStorage(String urlPath) async {
final name = urlPdf.split('/').last;
ProgressDialog pr;
pr = ProgressDialog(context, type: ProgressDialogType.Normal);
pr.style(message: "Download file ...");
try{
await pr.show();
final Directory _documentDir = Directory('/storage/emulated/0/MyDocuments/$name');
await dio!.download(urlPath, _documentDir.path, onReceiveProgress: (rec, total){
setState(() {
_isLoading = true;
progress = ((rec / total)*100).toStringAsFixed(0) + " %";
print(progress);
pr.update(message: "Please wait : $progress");
});
});
pr.hide();
_fileFullPath = _documentDir.path;
} catch (e) {
print(e);
}
setState(() {
_isLoading = false;
});
}
And this is my screenshot app with progress_dialog package.
just need a little tweaking :
Future _downloadAndSaveFileToStorage(String urlPath) async {
final name = urlPdf.split('/').last;
ProgressDialog pd = ProgressDialog(context: context);
try{
pd.show(
max: 100,
msg: 'Preparing Download...',
progressType: ProgressType.valuable,
backgroundColor: Color(0xff212121),
progressValueColor: Color(0xff3550B4),
progressBgColor: Colors.white70,
msgColor: Colors.white,
valueColor: Colors.white
);
final Directory _documentDir = Directory('/storage/emulated/0/MYDocuments/$name');
await dio!.download(urlPath, _documentDir.path, onReceiveProgress: (rec, total){
setState(() {
_isLoading = true;
int progress = (((rec / total) * 100).toInt());
print(progress);
pd.update(value: progress, msg: 'File Downloading');
});
});
pd.close();
_fileFullPath = _documentDir.path;
} catch (e) {
pd.close();
print(e);
}
setState(() {
_isLoading = false;
});
}
