Flutter: Progress dialog is not hiding - flutter

Question

I am using progress_dialog 1.2.0 package to show a progress dialog in my app, it is showing when I call pr.show() but not getting hidden when I call pr.hide():
onTap: () async {
pr.show();
print('clicked custom category');
print(categorylist[index].catName);
print(categorylist[index].catId);
// await getAllProductsInCategory(categorylist[index].catId);
setState(() {
catId = categorylist[index].catId;
myinitlist.clear();
myinitlist = List.from(productList);
pr.hide();
});
},
When I uncomment that getAllProductsInCategory() function it hides the dialog.

Answer 1

Try with :
onTap: () async {
pr.show();
print('clicked custom category');
print(categorylist[index].catName);
print(categorylist[index].catId);
setState(() {
catId = categorylist[index].catId;
myinitlist.clear();
myinitlist = List.from(productList);
Future.delayed(Duration(seconds: 3)).then((value) {
pr.hide().whenComplete(() {
print(pr.isShowing());
});
});
});
},
or :
onTap: () async {
pr.show();
print('clicked custom category');
print(categorylist[index].catName);
print(categorylist[index].catId);
Future.delayed(Duration(seconds: 3)).then((value) {
setState(() {
catId = categorylist[index].catId;
myinitlist.clear();
myinitlist = List.from(productList);
pr.hide().whenComplete(() {
print(pr.isShowing());
});
});
});
},

Please use await keyword when you are using async calls to start progressDialog & hide:
await progressDialog.show();
await progressDialog.hide();
Example:
Add the Package:
dependencies:
progress_dialog: ^1.2.4
import 'package:progress_dialog/progress_dialog.dart';
Create and initialize a ProgressDialog object inside the build() method passing context to it.
Initialize the ProgressDialog object:
final ProgressDialog pr = ProgressDialog(context);
By default it is a normal dialog to show some message, if you would like to use it to show percentage of progress done, specify the optional type parameter and specify if you want your dialog to dismiss when back button is pressed isDismissible parameter (Optional):
//For normal dialog
pr = ProgressDialog(context,type: ProgressDialogType.Normal, isDismissible: true/false, showLogs: true/false);
//For showing progress percentage
pr = ProgressDialog(context,type: ProgressDialogType.Download, isDismissible: true/false, showLogs: true/false);
> Note: Please initialize the ```ProgressDialog```, where you have availability of the context
Style the progress dialog (Optional)
pr.style(
message: 'Downloading file...',
borderRadius: 10.0,
backgroundColor: Colors.white,
progressWidget: CircularProgressIndicator(),
elevation: 10.0,
insetAnimCurve: Curves.easeInOut,
progress: 0.0,
textDirection: TextDirection.rtl,
maxProgress: 100.0,
progressTextStyle: TextStyle(
color: Colors.black, fontSize: 13.0, fontWeight: FontWeight.w400),
messageTextStyle: TextStyle(
color: Colors.black, fontSize: 19.0, fontWeight: FontWeight.w600)
);
Note: You don't need to use all parameters, all of them are optional.
Showing the progress dialog:
await pr.show();
Dynamically update the content shown out there
pr.update(
progress: 50.0,
message: "Please wait...",
progressWidget: Container(
padding: EdgeInsets.all(8.0), child: CircularProgressIndicator()),
maxProgress: 100.0,
progressTextStyle: TextStyle(
color: Colors.black, fontSize: 13.0, fontWeight: FontWeight.w400),
messageTextStyle: TextStyle(
color: Colors.black, fontSize: 19.0, fontWeight: FontWeight.w600),
);
Dismissing the progress dialog:
pr.hide().then((isHidden) {
print(isHidden);
});
// or
await pr.hide();
Navigating to next screens must be done after the completion of Future - hide(). See here for example.
Check if progress dialog is showing:
bool isProgressDialogShowing = pr.isShowing();
print(isProgressDialogShowing);
Use custom body
pr = ProgressDialog(
context,
type: ProgressDialogType.Normal,
isDismissible: true,
/// your body here
customBody: LinearProgressIndicator(
valueColor: AlwaysStoppedAnimation<Color>(Colors.blueAccent),
backgroundColor: Colors.white,
),
);
