Wow... I found your channel a few days ago and I must say I'm blown away... I would like to request if you can make a video on how to only run the intro pages one time in the application. I am very new to flutter.
That was dope af

Excellent work. Amazing!
You are very talented. Do you mind making videos on how to access phone permissions. Like fingerprint, file media, camera, microphone, contacts and so on. That would be really helpful. Thank you!

Thanks
all goooddss
Hey mitch, why did we use alignment property of container to place the smooth dot indicator, we could have used positioned widget right ?
thank you very much.
I have a question please:
how can I skip the introduction screens if I am old user?
so for and old user we skip directly to login page for exemple.
👍 Very useful video tutorial, thank you Mitch. 😊
No problem glad i could help ❤️
@@createdbykoko Hey Mitch, I was just interviewed by some experts from a tech company from Kolkata, India for a Flutter app developer position. After the first round technical interview I was shortlisted for the second round technical interview and I just came after attending the interview. However, I'm new to Flutter development but I believe that I will get the job. I think Flutter is really easy and you are helping me alot! Thank you so much Mitch! 😊
Yo one thing instead of using navigatior push use pushReplacement to completely dispose the intro screen from the stack so people won't see it when the want to exit the app and one more thing it's absolutely necessary to dispose the page controller in the dispose method of the stateful widget to avoid memory leaks
Ohh nice.😁
Is there a way to display the intro screen only once when user opens the app for the first time? n later it opens the home screen on subsequent opening of the app?
@@unlockedplucky209 absolutely yes. You can use shared preferences to store a bool like introShown when the user launches the app and only show the intro screen if that value is not set
@@unlockedplucky209You could use shared prefrences, or firebase for this. depends on the context you're doing it
You are awesome
Hi Koko virtual code mentor, you missed adding that smooth page indicator won't work without importing packages, but great video. Thanks
What software or site do you use to make the presentation video of the app ?
it´s poss change the scroll view in each page with only one pageview? example page1 to page2 horizontal, page2 to page3 vertical,
Very Good :)
Keep going
💜💜💜💜
Create a video about shared preference with this Introduction Screen
i haven’t tried yet but instead of creating a bool to track can we check the index throught the controller for condition of next and done.In this way we dont need setstate i think .
Hey i wanna ask something, why after we go to the homepage and press the back button it going back to the onboarding screen again?
Thanks bro, also, I would store in shared preferences or with Hive package the fact that the introduction screens have already been viewed, so they will appear only the during the first launch of the app
This is a great point! Thank you
How to do that bro
can you help me out a bit to stop relaunching the intro page every time I open my app?
@@unlockedplucky209 just use the shared_preferencies package and create a pair of key value with key of introduction_seen. By default it’s false and when the introduction has been seen, set it as true.
Before displaying the introduction, check if the introduction_seen value in shared_preferencies is set to false 👍
Can you please create a course for flutter UI?
Is it possible to share information between screens ? Let's say I'd like to register something that requires 3 or mores steps and each page the user would provide individual info for that specific step. Then on the last page the request would be sent to API. Is it possible to share information (data) between the screens ?
💯💯
Will this page be shown only at first run?
how can I get animated gif image like this?
How ican run vscode with emulator android??
❤
💘
Omg! Your content is told. Greetings from Nicaragua!
Which emulator do you use?
awesome..mm
unable to use smooth page indicator
Where can I find the code?
How do you skip the intro screens and go straight to Home after the user went through this after install?
Create a bool variable and save it in a json file.
Then read that file at the start of app to check whether the user has seen the onboarding.
Thank you, nice tutorial :) But this intro screens opens everytime when I re-run app. How can I prevent it? It should open only for the very first time, right?
did you get the answer?
dispose the widget and use navigator replace
Please also add complete flutter course for beginners 😏
I have something in the works for that 👨🏽💻 coming real soon ✌🏾
@@createdbykoko i cant wait for it 😲
@@createdbykoko yey :)
waiting or it
hey what about skipping introScreen for existing user ?
Shared preferences or hive will help with that!
honestly ur channel is the best very simple to learn with u @@createdbykoko 💜💜
How can I only make these show once?? Please make new tutorial.
State and get_storage one would imagine
Or only show it after sign up / first sign in
Is this Java or kotlin?
Neither, this is flutter
i have lot of errors please help
What does the error say? I can help
@@createdbykoko im talking about the red lines under the codes im a begginer btw
@@zyltho yup that’s fine. If you hover your mouse over the red squiggle, it will tell you what the error is
@@createdbykoko ive just wrote those yet
@@createdbykoko Hi I was struggling to understand the code to make it work and I did thank God he helped me, you also did but nothing shows up I have no errors or anything nothing shows up
heres onboarding_screen.dart file
import 'package:flutter/material.dart';
import 'package:qranic/intro_screens/intro_page_1.dart';
import 'package:qranic/intro_screens/intro_page_2.dart';
import 'package:qranic/intro_screens/intro_page_3.dart';
import 'package:smooth_page_indicator/smooth_page_indicator.dart';
class Onboarding_screen extends StatefulWidget {
const Onboarding_screen({Key? key}) : super(key: key);
@override
// ignore: library_private_types_in_public_api
_OnBoardingScreenState createState() => _OnBoardingScreenState();
}
class _OnBoardingScreenState extends State {
//controller to keep track which page we are on
PageController _controller = PageController();
@override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: [
PageView(
controller: _controller,
children: [
Intropage1()
,Intropage2()
,Intropage3()
]
),
// dot indicator
Container(
alignment: Alignment(0, 0.75),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
// skip
GestureDetector(
onTap: () {
_controller.jumpToPage(2);
},
child: Text('skip')),
// dot indicator
SmoothPageIndicator(controller: _controller, count: 3),
//next or done
GestureDetector(
onTap: () {
_controller.nextPage(duration: Duration(milliseconds: 500), curve: Curves.easeIn);
},
child: Text('next'),
),
],
)),
],
),
);
}
}
heres main.dart
import 'package:flutter/material.dart';
// ignore: unused_import
import 'onboarding_screen.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return const MaterialApp(
debugShowCheckedModeBanner: false,
);
}
}
but import 'onboarding_screen.dart'; is unused
In the skip button use this => _controller.animateToPage(
2,
duration: const Duration(milliseconds: 500),
curve: Curves.easeIn,
);
