Android bottom navigation appears when pressing on Flutter bottom navigation bar

I'm using SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.top]);
to only display the top system overlay (Where you normally see time and notifications) and disable bottom navigation of the device (3 buttons in android or slider in IOS).
Problem is that when I try to press the Bottom Navigation Bar of my Flutter application, it automatically activates the bottom bar of the system, blocking out the bottom navigation bar of the app.
Resizing the app is not suitable for me. I don't want this to happen, and system navigation should only appear when user slides from the bottom.
Help is appreciated.

Can you share your code so that I can have a better Idea,
// to hide only bottom bar:
SystemChrome.setEnabledSystemUIOverlays ([SystemUiOverlay.top]);
// to hide only status bar:
SystemChrome.setEnabledSystemUIOverlays ([SystemUiOverlay.bottom]);
// to hide both:
SystemChrome.setEnabledSystemUIOverlays ([]);
//to bring them back:
SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values)
Implement the in your code and it should work.

Hiding default navigation bar in app on Android devices

Currently working on a fullscreen mobile app, building using react-native. I have managed to hide the status bar and default navigation bar on Android devices. However, when I start to put in text input tags that prompts a keyboard on the screen, the default navigation bar re-appears and could not be hidden even I've dismissed the keyboard.
Is there any way to prevent the default navigation bar re-appears when the keyboard pops up?
The reasons are that I need to remove the navigation bar to have enough space to locate the needed components on the app UI design. If the navigation bar re-appears the design will be messed up. Thank you for any advice.

I think this is what you're looking for:
static navigationOptions = {
header: null,
};
Put this on top of each screen

Hide navigation bar, android 4.2+

Is it possible to hide navigation bar on e.g. tablets in activity, so it does not appear when user is clicking on the screen?
I want it to appear only when user is swiping from bottom to middle of the screen, just like in e.g. Real Racing 3.
When I use:
myView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Unfortunetly navigation bar is hidden, but when user is clicking, it appears again. I want it to work only with this swipe gesture. How it can be achieved?

This is a platform behavior. Apps do not have the sort of control of the navigation bar that you are looking for, and for good reason. All it takes is one app not implementing a way to show the nav bar and the user is stuck. You will have to design your app with the platform's behavior in mind.

Android Layout does not allow user to pull down notification bar

I am writing an App using MonoDroid and for some reason I cannot pull down the notification bar from the top of the screen. I am thinking this has to do with my layout, but I am not sure. I also notice that when my App is running I do not have the bar at the top showing the battery, time, signal strength, etc.
So, my question is, what do I need to do to allow the user to pull the notification bar down? And how to show the info at the top of the screen?

I suspect you have done something to make your app appear in "Full Screen" mode (this will turn the home, menu and back buttons on the bottom of the screen to dots, and hide the navigation bar.
I believe this is called "lights out mode". Here is one SO question asking how to turn it on (maybe it will help you turn it off as well): Hide ICS back home task switcher buttons

Maybe your theme is
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" ?
It hides the notification bar. Change to a non-fullscreen theme to make the the notification bar visible.

On Android Honeycomb how do I add option menu to the home bar at the bottom of the screen?

I'm On Honeycomb (3.1) and my first problem is that I don't know what is the name of the bar at the bottom of the OS (appears in every application). I've seen some apps add options to this bottom bar (it has by default the back button the home button and the show active programs button, besides the watch, battery indicator and signal connection strength). When a certain program uses options it sometimes adds them to this bottom bar (it is usually seen as a grid-like icon next to the show active programs buttons, which you can click and a menu pops up.
I've described it as best as I can, but My question is simple: how can I create a menu like this on in my app?
Thanks for any help!
EDIT:
Ok, I've just read it's a compatibility feature. And it's not supposed to be there in an Android App.
I feel stupid...

That is the "system bar".
I've seen some apps add options to this bottom bar
This happens automatically for applications that set up an options menu using onCreateOptionsMenu(). However, once the application switches to the Honeycomb look-and-feel (e.g., via android:targetSdkVersion="11"), the options menu moves to the action bar.
how can I create a menu like this on in my app?
Long-term, you do not want to do this, because it means that you will not have the action bar and will not look like you belong on Honeycomb, Ice Cream Sandwich, etc.
Short-term, simply do not have android:targetSdkVersion="11", and implement an options menu as normal.
