I am trying to create a simple button in flutter to open a google maps with a simple location with these coordinates:
31.233568, 121.505504
But evrytime i try to start url_launcher or map_launcher it dosen;t work and gives me this error.
I am getting unhandled exception error for map_launcher and url_launcher both.

In fact another package, google_pay also dosen't work.
I have imported FireBase can that be a reason for my problem?
The error:

I have searched forums which say that my MainActiviy.java file must be edited but i can't find that file anywhere.
I have tried starting a new project and the map opens fine in a new project with just url_launcher and no other plugin installed I have tried flutter clean and flutter upgrade and updated android studio.
I don't know what to do i have read many answers but nothing seems to work.

Hi @thechawla225
have you restarted you app after adding these dependencies and executing flutter pub get, right?

in your AndroidManifest.xml do you have io.flutter.embedding.android.FlutterActivity?

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="bug"
        android:usesCleartextTraffic="true">
        <activity
            android:name="io.flutter.embedding.android.FlutterActivity"
...

@VladyslavBondarenko Yes I have restarted the application multiple times after installing these dependencies and have also in fact restarted my PC. I do notice that some lines seem to be different in my AndroidManifest.xml file so here is that part that u mentioned here:

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="vatsalya2"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"

Should I change the following lines in this file or add something new ?
Thanks for replying so quickly.

In addition, there seem to be these red lines in these lines as posted in this screenshot below :
(I noticed them just after reading your post so I apologize for not seeing this earlier.)

@thechawla225
you say that you can't find MainActiviy.java. Do you have then MainActivity.kt in android/app/src/main/kotlin/<package_name>/?

Is it like this?

package com.example.newapp

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}
