I want to create an application, when I enter any mobile number it should give me current location of that number.
Guys please help me if it is possible then tell me how it is possible ?
you cant get the location from cell number !!!!!
though there are some applications in some countries which they do something like this but the mechanism is different.
how they work is, user registers in their app and they use Cell Number as username for registering users. then this way they can tell you the location of other users by phone number. (you can just see users' location who registered in app)
since there isnt any way to get the cell number programatically so such system you want cant exist unless the user gives you the number and you verify it some how (sending code sms and etc) and thats what the apps i mentioned are doing.

I want to make a chat app in which all features of chat like messaging, sharing video, image, and emoji, etc. I found a lot of tutorials for that but no one says how to chat with only those you know or have in contacts to prevent unwanted disturbance to the users from others. How to make such an app with flutter?
One way is by reading all the contacts number form the phone and then check if that phone number is registered
One feature/method I can think of is using referral/invite. The person can only join the app only if he is invited and the invitation is approved by the admin. This way you can have control over who accesses your app.

We want to develop application which used to share important data in secure way. Idea is:
Data to be exchanged between phone A and phone B (and vice versa) when users “Tap” the phones together. The date, time and location of this action is to be recorded.
This should work anywhere (in buildings or in rural areas where there is no mobile signal coverage), and work cross platform (iOS, Android, Windows).
we want to know is it possible to develop such application ?
Thanks,
Yes, you can 'bump' phones and send over Bluetooth. You would use the accelerometer of the phones to detect the 'bump' part. The date, time and location you can pull straight from the devices (given you have GPS permission).
It would be a lot of work to develop right, especially across multiple platforms, and I believe an app like that already exists, for sharing contact information.
Also for future reference, you're probably getting down-votes because you're not asking specifically about code. Best of luck.

I have created an android application, in which i have to find the current location of the mobile. For example using my application i have to find my friends current location.If i enter the mobile number the current location of my friend has to be shown in map.Its not necessary that my friend mobile to be smart phone. How can i track them using their phone number without using GPRS? Please help me.
You can get Location if you have Internet Connection(GPRS or WIFI), otherwise you Can not get Location, Because to get Location, your Phone need to communicate with (Google Maps) and then they get your Longitude/Latitude and then give you the facility.
If you need to check your Friend's Location, for that you need your Friend Latitude/longitude Information.
But you must have Internet Connection.

Is it possible to send an SMS from an Android app and change the sender number, so that the receiver will see the SMS as coming from someone else?
I'm not doing this for pranks or illegal systems, it's something necessary.
Thank you
I don't believe this is possible, and would find it highly questionable if it were.
If you're simply looking to give someone the ability to send a message to a number using your app as a service. Then try using Twilio www.twilio.com or something similar where you can pick a number and send message to others. Although you will be paying for the SMS's that are sent and this may not be what you want.
This is possible, but you need a sms server/gateway or an online provider which does it for you. You could even enter text as your number (companies like facebook and google do this).

I need to create an application that will show me on a map to all users who have installed my app within x distance.
It wondered if I need to save the coordinates of each user periodically in a database and read the position or is there another option
Tracking the user's location in a database will likely be your easiest option. It will also scale well. If you are only tracking a couple users, you could use another simpler data storage mechanism like an XML file, a text file, or even some sort of Application Level Variable.
I'm sure that you have done some research on how best to track your users, but this is a pretty good starting point, if you don't have one already. They are storing each location in a local database on the phone, so I'm sure that you could very easily modify it to send that same location to a web service or something.
