Can any one tell me how to open another app using flutter?

Question

I want to open a bunch of music app links using links data I have in firebase. I want to open, amazonPrimeMusic, Ganna, Spotify, Wynk, JioSavaan to name some.

Widget buildResultCard(data) {
  List items = [Text(data['Ganna']),
    IconButton(icon:Icon(Icons.all_inclusive),
      onPressed: ()=> {Text("Ganna")}
    ),

    Text(data['Wynk']),
    IconButton(icon:Icon(Icons.all_inclusive),
      onPressed: ()=> {Text("Ganna")}
    ),

    Text(data['JioSavaan']),
    IconButton(icon:Icon(Icons.all_inclusive),
      onPressed: ()=> {Text("Ganna")}
    ),

    Text(data['PrimeMusic']),
    IconButton(icon:Icon(Icons.all_inclusive),
      onPressed: ()=> {Text("Ganna")}
    )
  ];

  return ListView.builder(
    padding: EdgeInsets.only(top: 20),
    itemCount: items.length,
    itemBuilder: (BuildContext context, int index) {
      return items[index];
    },
  );
}

when I tap the button in the list it should open up the particular app for which the link is, for example for AmazonPrimeMusic link, it should open the Amazon music app.

Hello you actually need two packages. Check the versions before you use them. First of all you need the id of the app. For example for facebook lite the id is com.facebook.lite. You acn find the id if you go to playstore click share and cope the link. The link for facebook lite is https://play.google.com/store/apps/details?id=com.facebook.lite from this one you can easily understand that the id is after "id=". Its the same on the other apps too.

device_apps: ^2.1.1 url_launcher: ^6.0.3

try {
  ///checks if the app is installed on your mobile device
  bool isInstalled = await DeviceApps.isAppInstalled('si.modula.android.instantheartrate');
  if (isInstalled) {
     DeviceApps.openApp("si.modula.android.instantheartrate");
   } else {
     ///if the app is not installed it lunches google play store so you can install it from there
   launch("market://details?id=" +"si.modula.android.instantheartrate");
   }
} catch (e) {
    print(e);
}

so the code above check if you have already installed the application. If you have done it it will lunch the application if not it is going to open google playstore so you can see it there. It works only for android devices.
