I took Flutter & Dart course on Udemy. In Section4 after making the personal expenses app. Whenever I restart my app the transaction history is gone. I wanted to know how to save them locally. I am aware in section6 some way of saving is shown but it just is too cumbersome.
Could anyone help me with it.
Thanks.
You can ask directly in the Udemy course forum, they will know about the sections that you are talking about.
Also here you have a cookbook about reading and writing files: https://flutter.dev/docs/cookbook/persistence/reading-writing-files
Also, you can use packages like Local Storage

I need some help! I have built my front end app + set up perfectly my public CloudKit container. I am just trying to share the data of my app between not iCloud users…it’s a hell… The knowledge request is over my skills. I have spent several weeks to try to solve this problem..,.and still…haven’t found the solution.
I don’t think I need vapor framework (because I don’t need to edit the data I am sharing).
Up to now I was able to download the data from iCloud public container inside the terminal following this old tutorial of 2016 (following the bonus "server-side cloudkit access” part two, cf. link under)
https://www.kodeco.com/997-cloudkit-js-tutorial-for-ios
but I am not able then to put the data inside a html page to share the data of my app through any kind of my platform.
I have tried to follow these two examples to put the data of my cloud kit container inside a notion html page
https://www.twilio.com/blog/manipulate-notion-database-using-node-js
https://developers.notion.com/page/examples
I am lost … I am not able to adapt this two examples inside my project.
Is there some one around to help me and make a simple example or give me some guidelines?
I am trying to create a flutter app using the ML model from the below link.
https://www.tensorflow.org/lite/models/style_transfer/overview
I haven't played with Flutter but there are some promising articles article 1 article 2 article 3 that gives code snippets to insert tensorflow lite dependencies, to make assets folder and load models. You can check them and I hope you get a first idea how to proceed. Style transfer is a medium to hard coding project though. I suggest to start from simpler tasks as classification problems.
Happy coding
I have used this style_transfer model in flutter app before. unfortunately, I've lost that code (I did not use git). But I can give suggestions on that.
For using this custom model you will have to use https://pub.dev/packages/tflite_flutter.
The trick here is you will have to see model's input shape (image_shape=(384,384,3), style_shape=(256,256,3) and output size (shape=(384,384,3) and also shape of bottleneck). You can resize image using https://pub.dev/packages/image.
with these two, you are good to go. Sorry for bad english and I know I am too much late but maybe someone else will find it useful.
Happy coding!
Edited: So I have found the code. I stored a copy of it in my google drive. I have uploaded it on github https://github.com/Rizwan2613/style-transfer. Please do read Readme file. Thanks
There is a recently published flutter plugin for integrating an arbitrary TFLite model.
https://pub.dev/packages/tflite_flutter
Please see the README of the pub package and see how you can bundle the .tflite models and how to load / run them in flutter.
There is a blog post on how to use this flutter plugin, but it uses a different model (text classification) as an example.
https://medium.com/#am15hg/text-classification-using-tensorflow-lite-plugin-for-flutter-3b92f6655982
You can upload custom tensorwflow model to firebase ML KIT (custom tab), and integrate with firebase API in your flutter project.
noob here.
I did an app on ionic, is pretty basic just images, buttons and text; the buttons are linked to another page and stuf like that, i mean there is no logic still like a loop or something.
What i was asked is to update the project of the app that is on ionic1 to ionic4 because someone that is willing to help me works with ionic4 and not ionic1.
Is there a guide for noobs to do this? i have been looking on google but nothing pop up
i read this but to a noob makes no sense https://ionicframework.com/blog/a-guide-for-migrating-to-ionic-4-0/
But the solution is kind of like this:
"Then, create a new Ionic 4 application and begin porting features over. Once the team is comfortable that the new app is stable, you can shut down the Ionic 1 app"
Thanks in advance!
The reason why there isn't a straightforward guide is because an absolutely huge amount of changes were made.
Take a look at the breaking.md document on the repo, its over 1000 lines long:
https://github.com/ionic-team/ionic/blob/master/angular/BREAKING.md
There is a linting tool that could help you identify the main areas that you need to migrate, and if it's just a simple app like you say then it could do a lot of the work for you:
https://github.com/ionic-team/v4-migration-tslint
Beyond that the only real way is to look at every tag and then search it and see if its listed in the breaking change. If it is then update it.
The reason why the official advice is to make a new app and port features over is that otherwise you will have a non-working app basically forever up to the last moment where it starts working. Not the best way to learn so they say start with a new working app and build bits in it that are already Ionic 4.
I started looking into OwnCloud app development to add some capabilities I would like to my server. To me it seems like Apps can't modify anything like the Login page or User Management page. Is this the case?
I want to build a user registration app and would love to integrate it into the user management page (if not and it has to exist as its own app page not a big deal). The one big problem I see so far is not being able to add a "Register" link to the login page. I could just go in and add it to the source manually, but I would like to keep the App self contained so others can use it too.
If this is not possible to do in an App I may just need to modify the core application and then see if they will accept my feature addition in a pull request.
Thanks to anyone who can shed some light on this for me. I don't want to waste my time trying to figure out how to do it with an App on the platform if it wont be doable.
After a lot of digging around I did figure out a way to do this.
In the App's app.php file, you can force a script to be loaded if the plugin is enabled:
$api->addScript('script_name'); // without .js
In that script jQuery can be used to add the elements to the page where you need them.
This was a good solution for me since I only needed to add a single button to the login page. I can see this being a bad idea if you want to make vast modifications. At that point you might as well just create a separate page that you have full control over.
I'm currently working on an iPhone project where i want to present to the user spesific terms from wikipedia. I'm facing tow difficulties right now:
1. I want the specific content to work offline.
2. I want to show the relevant pictures as well.
I need to find the most efficient way to do it, can someone advise ?
You could get the content online and cache them in the app DB. If necessary you could prepolutate the db directly in you app. That way some terms would already be available.
