enter image description hereI just want to know some thing,.. I am practicing API Integration in Flutter.. From a Video tutorial I made a weather app which tell us weather but in the app I have declare a cityname: every time I open the app it tells me the weather of that specific city,( this is all I made through a tutorail)
then I made some changes in it and make a texfield for city and when I enter any city it tells me the weather of that city..
Know I want that the app detects the location from user and tell the user weather of his location in which he is,, for that i use GEO locater package and when i open the app it is working fine but when i send the apk to a friend which is in a different city he got an error which is :

I’m trying to call an API with a custom Body but I always the same error.
Error 400
And the API return “can’t json/yaml decode the argument”

I have data from the API as below

Currently, I have complete my frontend design. Now I want to call the API to submit the data. When user click “Submit” button, it will pass all the inputted data and call API to insert to database. How to call API with all parameters in flutter? This is my attempt.

I’m struggling with implementing ratings and review in my flutter App. When a user clicks on the rating star and drops a review, it should be stored and displayed on the UI. I’ve made request to the endpoint handling that and the model for it, I need help with the handling the GetX controller and passing it to the UI.

I was tasked on developing a form for registering vehicles and some information about them, it can do it manually but was tasked to add a SearchBar that uses the NHTSA API to fetch this data automatically
