Hi Johannes, thank you for your great tutorials! I have a question: I want to change a variable (different assets for dark and light) in my home.dart based on whether dark mode is activated or not. Do you know how/if that is possible?
God bless u man
very nice explanation
Thank you, Naushad Husain! đ
Thanks for your helping Us
@johannes I have a question!! In the minute 7:14 why didnÂŽt you use the top reference to the provider instead of the one that you put in the onchange callback? I donÂŽt understand the difference between both... :s Thanks a lot!!!đđŒđđŒ
@Johannes Milke Thank you so much for this wonderful tutorial. Could you please make a tutorial focusing on theming form fields such as TextFormField, radio button, checkbox and so on using ThemeData.
@@HeyFlutter Thanks for adding it to you todo list.
I use vs code for android and ios simulation via flutter on my android emulator and the theme doesn't work on both platforms is use the custom ThemeData class. Do you have any solution?
bro, thanks for the video, it was really easy to understand. but I have a question what about selected icon theme?
Hi Johannes, great video. All other examples use static methods, but you've gone with a class and methods, any reason for that?
Thanks.
Good explanation so far. I can easily get it. But i saw that there are some missing or skipped step which will be hard for beginner to understand.
Why scaffold rebuilds many times if we change theme? It should rebuild only once if we change theme right?
Very nice ui...
The best vdo.
How to change the system navbar color based on light and dark mode
Wie geht es das bei der NavigationBar kein Rand darum ist bei mir ist wegen der margin immer ein rand?
Great đ
@@HeyFlutter I have been learning flutter for about a month. Your videos are awesome and easy to understand. Thank you. đ And keep rocking.
How to save the preference and load the theme in startup?
Teacher the theme applies when system dark mode is on but the switch doesn't turn on...Please make a video about it(I copied it exactly as your vid)
Hi! I was wondering if it were possible to have a gradient background for the scaffoldBackgroundColor. Is there a way to implement this?
@@HeyFlutter Thanks! It works now. Your videos are really helpful. Keep up the great content!
how do dark mode stay active when user closes app and revisits app?
How can we implement with Multiple Providers? I could not please help sir đđ
Will this work when i close the app from the background and restart, will it show the selected theme again?
I have used custom colors in my app like one container having a certain color and then another container having a different one (same goes with text widget), so doing a theme like this way maybe won't solve it. so do I have to use ternary for it everywhere? or is there a better solution?
Hey đ, Anas Yousuf! Check out this solution : stackoverflow.com/a/63954659 I hope it may help you
Wonderful Video, i was wondering, is there any way how i can save the state? when hot reloading the theme returns from dark to light ?
Thank You UJ! Follow this link: stackoverflow.com/questions/69824460/save-full-state-of-a-flutter-application
I hope you will get your answer đ
15:12
Thanks!
Very lovely video, simple and easy to implement. How do I have the theme chosen to flutter storage they don't get the default system theme after choosing a theme
Thank you, Caleb Oruta! đ it's simple you can stop listening to device's current theme once user selected from app
I followed all the processes till the end but only got the UI as in the first section. Why is that?
So in the bonus section, you set theme mode to ThemeMode.system; when I change display to darkmode and start my app, the switch isn't toggled on automatically, I have to click it twice. can you help me with this?
@@HeyFlutter Thank you very much brother :)!
Hi, first of all thank you for all! you are a great developer.
I have a question, why at 7:14 you use two Provider.Of and not re-use the same?. Thanks
Thank You Ivo Mele! Follow this link: stackoverflow.com/questions/58774301/when-to-use-provider-ofx-vs-consumerx-in-flutter
I hope you will get your answer đ
Anyone know of a way to implement this in the settings_ui tutorial? Whenever I toggle the switch on the settings page, it bounces me out to the homepage. I'd like for the toggle to work but keep me in the settings page. Any ideas?
I'm facing the same problem , did you find any solutions ?
hiii @johannes Mike i implement this video in my app but get problem is if a reload that app my sleected the i.e dark theme turn it into light i search many solutions but i didnt find any relative plz help me in this ...
Yes, because in this tutorial he hasn't used shared preference to save the theme and i don't know why he has still not updated his github with shared pref. This tutorial is incomplete and of no use.
Great tutorial kind Sir! My question is, how do I change all the colors, etc. if my app does NOT have a theme switch, but only goes by the system settings? Thanks!

How to save theme in local?
man your a really mvp for flutter developers, you even let us thing what actually missing in some of your video on which is good for our critical thinking. i have a question when i change the theme inside the app and close it, it return to its default theme which is system themes? how can i stay it in the dark mode after i close the app and the system theme was light mode?

Hi Johannes, greetings from Brazil! I want to create a custom navbar, just like yours. Is there any video you're teaching how to make it?
Thank You Lucas Monteiro! Follow this link: pub.dev/packages/custom_navigation_bar
I hope you will get your answer đ
dunno if anyone would see this but is there a way to change the switch into a button?
Yes, @phosepio. đyou can change it. It's pretty easy. But still, I prefer switch is a better option for better UI/Ux.
one issue i am facing when restarting the app the theme reset
Thank you, MusiGod! đ. Try to provide enough details with your question whenever you face any issue.
Thanks for a great tutorial! Would you know how to support dark mode on a CupertinoApp?
@@HeyFlutter Oh, just watched this video, but it is using MaterialApp, which supports themeMode and darkTheme. CupertinoApp doesn't đ€
I want to change the theme with a dropdownmenu, some can help?

how to make the switch off for first open the apps?
Thank You @ReyRendryo! Follow this link: stackoverflow.com/questions/60792667/flutter-switch-toggles-off-on-its-own
I hope you will get your answer đ
Might be a dumb question. But does this save upon restarting the app? Also does it save across different pages?
@@HeyFlutter sweet! Thankyou! Love tutorials btw!!!
@@HeyFlutter How do i set it acros the pages tho? I cannot seem to make it the same across different pages if i change it
can you make dark mode state changes using getx package instead of provider package
@@HeyFlutter also picking multiple images from gallery and displaying it on screen đ cause using image picker we can only select one image there are lots of package like multi image picker but it doesn't work well hope you will make video on this topic
5:30 Why did we use *get* there? Couldn't we just give isDarkMode the value directly?
Hey, Broteen Das đ Getters and setters are part of OOPS, you can use directly also
@@HeyFlutter Got it sir... I'll look more into it
anyone who knows how to i persist theme data in my phone.
Thank You amanuel gulilat! Follow this link: stackoverflow.com/questions/68267016/how-to-save-the-state-of-the-app-with-the-current-theme-in-flutter

Hello I'm using this code after watch video. I like code but if you use with shared prefrences for your code, It will be better.
Thanks for the suggestion @peacefulnaturalworld8964! đ
do you have a course on Udemy, I'd love to buy.
we all would buy đ, you are good teacher.
Thank You Arvind Kumar!. Learn about it here: johannesmilke.teachable.com/p/home
i want to know switch theme by using icon button
@@HeyFlutter yah I got it thank you.. Dude..
simply explained.....excelent brother....today i discovered something i would like to share with you......
If someone helps others.. Who helps him
If someone serving others who is serving him
If anuraag said hurtful things to shivuBaby then who said such things to anuraag
It's all balanced by God
Mystery solvedđȘđđ
If you start loving everyone God will start loving youâ€đâ€đâ€... Universal balanceâïžâïžâïž
This should be unconditional... If you put a condition on â€... Then it will cease to be â€....

Pls update your github with shared pref. so that people can really use this in their app. How can a tutor like you miss that. People follow you for some reason and you should make it worth. Don't give them reason to unsubscribe you. Waiting for the update. Your 10 mins time could save beginners 5 hours, first to understand the reason and to do this all over again in the app by following somebody else.
@@HeyFlutter Thanks. Hope you do it soon and mention it in pinned comment.
and i thought kotlin was difficult
Thanks for your feedback, Angad C! đ
DISLIKE!
The selected theme does not persist when app is relaunched. There is no easy way to apply shared preferences method using this structure.
Dislike. Next time finish the project with Shared Prefs, don't scam people. We can do shit with this toggle switch if we lose all data when we leave the app. (Don't say 'oh here is shared prefs video', no, you should have placed it here already). Next time I see a state that you don't care to save, I will unsubscribe.
@@HeyFlutter It's not about me, but some kids that are just learning flutter. I know when I started, I followed a video to a work (I could just guess how it feels when they find out Dark Mode stops working every time they close an app). And, it's just 3 lines, initialize, setBool, getBool and done. Don't take my rant as a bad thing, you are still an amazing teacher.
@@HeyFlutter fix this pls, now i have followed your tutorial in app and now it is of no use and pls update your github and let people know.
you really don't know about flutter too much like a professional to teach. you just google it and copy past codes here. you even don't have enough experience with flutter. you are not theming like a professional. thanks god there is someone who is worse enough in flutter than me đđđđđđđ
Thank you, FTF Music! đ. We always learn and try to improve ourselves, you kind suggestion will help in that regard. Let us know what should we improve in our videos? Your suggestion will be highly appreciated.
For MultipleProviders use the context from the *builder* method and not the one MaterialApp is using.
Widget build(BuildContext notThisContext) {
return MultiProvider(
providers: [ ...],
builder: (useThisContext, child) {
return MaterialApp(
themeMode: Provider.of(useThisContext).themeMode,
...
);})}
