I am trying to implement a true caller like alert dialog in flutter. Since I am very new to flutter+dart, I was looking for any out of the box implementation. So far I have found system_alert_window but this creates the alert dialogue in JAVA and uses platform channels to communicate with it. My question is that if it's possible to do this is pure flutter+dart.
I do not know if this kind of dialogues has any special names, also in truecaller the dialogue is shown regardless the app is running or not. Can anyone provide some pointers?
Thanks
No you can't do with flutter
You can only go with Java.
Flollow the steps
your project > android > app > src > main > AndroidManifest.xml
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
add this permission on your Androidmanifest.xml file
after adding the permission add the below receiver class
<receiver android:name=".CallReceiver"
android:enabled="true"
android:permission="android.permission.BIND_JOB_SERVICE"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
the receiver class
ServiceReceiver.Java
public class ServiceReceiver extends BroadcastReceiver {
#Override
public void onReceive(final Context context, Intent intent) {
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener(){
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
System.out.println("incomingNumber : "+incomingNumber);
WindowManager windowManager = (WindowManager) context.getSystemService(WINDOW_SERVICE);
View view = LayoutInflater.from(context).inflate(R.layout.popup_window, null); // Code for inflating xml layout
int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
LAYOUT_FLAG,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
PixelFormat.TRANSLUCENT);
windowManager.addView(view, params);
}
},PhoneStateListener.LISTEN_CALL_STATE);
}
}
add the below xml file on the folder
your project > android > app > src > main > res > layout > popup_window.xml
popup_window.xml

You can use flutter_overlay_window. Its JAVA only but works fine. The example app has a truecaller like overlay demo. The other answer is correct, no it can't be done in pure flutter.

what i want is to setOnclickListener when button is clicked.
my button code:
maptrafic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(map.getMapType() == GoogleMap.MAP_TYPE_NORMAL || map.getMapType() == GoogleMap.MAP_TYPE_HYBRID){
map.setTrafficEnabled(true);
maptrafic.setImageResource(R.drawable.trafficmap_on);
}
else {
map.setTrafficEnabled(false);
maptrafic.setImageResource(R.drawable.trafficmap_off);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
}
});

just add app:layout_behavior="#string/hide_bottom_view_on_scroll_behavior" in your BottomNavigationView.

android:layout_width="match_parent"

....
app:layout_behavior="#string/hide_bottom_view_on_scroll_behavior" />
I know maybe it's late but I got the answer , two months ago I was searching and didn't find anything but a few minutes ago I found the solution and checked it works very well on Android Kitkat beyond, and decided to share it. I extract it from AppIntro Library ,here we go :
public void setImmersiveMode(boolean isEnabled, boolean isSticky) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if(!isEnabled && isImmersiveModeEnabled) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
isImmersiveModeEnabled = false;
} else if(isEnabled) {
int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
if(isSticky) {
flags |= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
isImmersiveModeSticky = true;
} else {
flags |= View.SYSTEM_UI_FLAG_IMMERSIVE;
isImmersiveModeSticky = false;
}
getWindow().getDecorView().setSystemUiVisibility(flags);
isImmersiveModeEnabled = true;
}
}
}
in your activity :
public boolean isImmersiveModeEnabled = false;
public boolean isImmersiveModeSticky = false;
and use it in your code :
setImmersiveMode(true,false);
or
setImmersiveMode(true,false);
Happy Coding :)

In your onCreate() method there isn't
setContentView(R.layout.activity_dashboard);
before the methods findViewById() which return null.
Use:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard); //<-- add the method
LoginBtn = findViewById(R.id.Login);
