QUESTION
I am trying to make a list of medicines in my mobile app. My data is in a local json file.
...ANSWER
Answered 2021-May-12 at 15:25The most efficient way to dealing with json data and rendering them is by creating models. If you are new to this QuickType can help you out with this.
Paste your json and you will get the code for the model. Next u can instantiate the model with your json data and use ListView.builder to iterate through your model and render the data.
Retroportal studio has a good video explaining this concept, take a look. I'm sure it will help you out.

dataI need on the page - Save
URLanddatato a json file
My code executes 1. and 2. perfectly but sometimes messes up with number 3. Output looks like this:
...ANSWER
Answered 2020-Jan-16 at 13:24The reason this is happening is that there is a potential mismatch between the callback result and the url variable in grabTheData.
Now there is a very quick fix for this, simple change the scope of the url variable like so:

I've make a translation service in nodejs :
...ANSWER
Answered 2019-Dec-10 at 19:07Simply await your call to the User model i.e let user = await User.find();
Also for the loop, try
let users = await User.find();
await Promise.all(users.map(async (user) => {
let sexix = await translate.GetSexFr(user.sex);
...
})));
Writing to file, you may want to use await fs.writeFile(...);. This will make sure file is written before processing the next.

hay guys, i'm new to JavaScript async programming, and i trying to take a file with only Longitude and Latitude and convert it to a street address
i converted my table to json file and imported the file to my little program, after that i'm trying to go through my array and get the address from the api, and i keep getting all sort of errors depends on my changes i do to fix the f**g thing
...ANSWER
Answered 2019-Jun-27 at 08:44I've tried your code out, there is only one mistake I can see, the latitude and longitude were the wrong way round, you were passing lng,lat whereas the API requires lat,lng. I suspect this is why you were getting the 400 error.
I've updated the code to handle error conditions a little better. Also I'd reconsider using inline function expressions, these make the code harder to read IMHO, maybe refactor them out!
