Hello I'm new in Flutter. when I try to import a new page to navigate new screen it shows error
It's not an error, but a warning. You are importing the module 'signup.dart' (that takes a small computational cost) but you are not using it.
Flutter is just trying to make your app faster by warning you about the packages you are importing but not using. You can simply remove that line (line number 5)
Navigate using these code:
Navigator.of(context).push(MaterialPageRoute(builder: (context) => SignupPage()));

I am trying to test if a button works in a flutter app.
If I was developing an Android native app, I'd make use of Log.i to print a message in the Logcat.
I want to the same exact thing in flutter.
What I've tried so far:
debugPrint
print
to import 'dart:developer' package to make use of the log function
Apart from this problem, I cannot open the console in AndroidStudio.
Here's a screenshot taken after looking fot the coslone in the search bar:

Any help would be appreciated !!!!
Hey there,

print('BUTTON CLICKED')
import 'dart:developer' as logDev; onPressed: () => logDev.log('BUTTON CLICKED', name: 'FAB -> ')

I have searched the package docs to return just to the previous screen & didn't find a simple solution
After some trials:
Navigator.pop(context);
I have a basic website using GetX for navigation. I have inkwells with ontap functions which navigate to a new view. Right now, if you right click these buttons there is no "open link in new tab/window", "save link as" or "copy link address".
Is there any way to get this functionality for Flutter Web?
Edit:
Since Flutter version 2.10, you no longer need to switch to channel beta for this.
Maybe I'm answering this late, but this may help someone in the future.
At the moment of writing this it is possible to be done, it is bugged on the stable channel, but it works perfectly on channel beta.
Just switch to channel beta:
flutter channel beta
flutter upgrade
Then follow this instructions to add url_launcher dependency to your project and import this package wherever you want to use it:
import 'package:url_launcher/link.dart';
And finally wrap any widget with this:
Link(
uri: Uri.parse('www.google.com'),
builder: (context, function) {
return InkWell(
onTap: () => print('Do something'),
child: Text('Right clickable text')
);
});
I run my application, but show this error. Before this i can run it. But now, It says "pr.dismiss is not defined in progress dialog." I have install package,and my code in flutter is not red colour but run it that got error in debug.
So how i can solves this problem?
I RUN THIS GOT PROBLEM
as per your source code you use https://pub.dev/packages/progress_dialog package for display progress dialog. so as per this package for dismiss dialog you need to use the below method.
pr.hide().then((isHidden) {
print(isHidden);
});
// or
await pr.hide();
So replace pr.dismiss() with the above method.
I'm working on a flutter project with VS Code and I ended up upgrading flutter. After upgrading, when i run my project i get a 'parameter format not correct' error:
I also get this:
After my app starts whenever I press something or try to type something or even scrolling the screen it looks like it's trying to cache something:
How can I solve this issue?
