# Changes
* Support RN 0.60
* Migrate to AndroidX
* Improve draw behind StatusBar (Preparation for #4258)
* Don't push BottomTabs when keyboard is displayed (Fixes #4005, #3424)
    - It won't be needed to toggle the BottomTabs when Keyboard is visible
* BottomTab badge and dot indicator are not animated by default on Android (parity with iOS)

# Updating from v2
v3 is currently in alpha. To update simply npm install `3.0.0-alpha.11` - `npm install --save react-native-navigation@3.0.0-alpha.11`.
Breaking changes are outlined below.

## Layout system changes on **Android**
* Parent layouts (BottomsTabs, Stack, SideMenu) are always laid out behind the StatusBar.
* Components (`component` and `externalComponent`) are measured and offset according to the StatusBar.

In this release, We're changing the layout system in order to provide better support for immersive and full screen apps. In this release we've improved support for drawing behind the StatusBar,  next we'll address drawing behind the NavigationBar. 

Use the `drawBehind` and `translucent` options to control the StatusBar
```js
statusBar: {
  drawBehind: true,  // will draw a screen behind the StatusBar
  translucent: true // Usually you'll want to have drawBehind: true when this is true
}
```

While this isn't a breaking API change - there are a few breaking side effects.

### How will my app be effected
1. When the keyboard is opened, BottomTabs will now be drawn behind the keyboard and won't shift upwards. This is in parity with the current behaviour in iOS. For the most part, this isn't a breaking change. Toggling BottomTabs when TextInput's focus changes won't be needed anymore.

2. While parent controllers are drawn behind the StatusBar, their background isn't.
This means that when transitioning from a destinations drawn under the StatusBar to a destination drawn behind it, the application's default background color will be visible behind the StatusBar.
If you application's theme is dark, you might want to change the `windowBackground` property to mitigate this:

Add the following to your application's `style.xml`
```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowBackground">@color/backgroundColor</item>
    </style>

    <!--This is your application's default background color.
    It will be visible when the app is first opened (while the splash layout is visible)
    and when transitioning between a destination a screen drawn under the StatusBar to
    a destination drawn behind it-->
    <item name="backgroundColor" type="color">#f00</item>
</resources>
```

## AndroidX migration
We've migrated RNN to AndroidX, please follow migration instructions in the react-native repo.

## Removed SyncUiImplementation
[SyncUiImplementation](https://github.com/wix/react-native-navigation/blob/master/lib/android/app/src/reactNative57WixFork/java/com/reactnativenavigation/react/SyncUiImplementation.java) was used to overcome a bug in RN's UiImplementation. This workaround was added to RN's `UiImplementation` in RN 0.60 (thanks @SudoPlz) and can be removed from RNN.

If you're using `SyncUiImplementation` your app will fail to compile after upgrading to v3. Simply remove the following code from your `MainApplication.java`
```diff
- import com.facebook.react.uimanager.UIImplementationProvider;
- import com.reactnativenavigation.react.SyncUiImplementation;


- @Override
- protected UIImplementationProvider getUIImplementationProvider() {
-     return new SyncUiImplementation.Provider();
- }
```

## BottomTab badge and dot indicator are not animated by default on Android (parity with iOS)
Showing and hiding badge and dot indicator are now not animated by default. Badge animation is now controlled with the `bottomTab.animateBadge` property and dot indicator with `bottomTab.dotIndicator.animate` property.

#### The following option will show a badge with animation
```js
bottomTab: {
  badge: 'new,
  animateBadge: true
}
```

#### The following option will show a dot indicator with animation
```js
bottomTab: {
  dotIndicator: {
    visible: true,
    animate: true
  }
}
```

closes #5228

Apply layout direction directly on views

This commit changes how RNN handles layout direction and adds support for LOCALE layout direction on Android.
Until now RNN delegated handling layout direction to RN's I18nUtil. This usually is enough but under certain circumstances
layout direction has to be applied directly on relevant views by RNN - usually when there are conflicts with another dependency
which handles RTL.

* Fixes unnecessary rendering of the last viewController in setStackRoot, Closes #5355

* Add setStackRoot unit tests

* Properly check setStackRoot animation and waitForRender of each child

* Read waitForRender from the last child of the new stackRoot

* Fixed indentation

* Use setStackRoot.waitForRender instead of push.waitForRender

* Fixed merge issues caused by the text editor

* removed eof newline

* Added a missing semicolon

* Variable toVC renamed to newVC for consistency

* Fixed indentation problems

When setting BottomTabs root, if one of the children was a stack with multiple children
and the top child in the stack had `drawBehind: true` while the bottom child had `drawBehind: false`,
sometimes the tabs' bottomMargin would be wrong since it was applied in onPreDraw.

Like all other options, buttons are applied when a screen becomes visible. This means that in a BottomTabs layout,
options are applied when a tab is selected. Since tab change happens involves only changing view visibility, and button creation take a bit long,
the buttons appear to flicker some times.

Fix white screen after calling setRoot() before rendering. Fix #5308

Under certain conditions, app launched event was emitted when the Android Activity isn't in resumed state. In this case, setting root isn't possible since ReactContext doesn't have an instance of the Activity (it can even be destroyed).

This PR ensures the event is emitted only when the Activity is resumed and root can be set.

new detox test command to run test cases when device is locked, one failing test case for Android when app is running by tapping on a notification and device is locked and the app is not running in the background.

When setRoot is called, modals should be destroyed, while Overlay components can remain on screen.

Add support for dot indicator to BottomTabs.

The default value for `UITabBarItem.title` is `nil` as specified by the docs:
> You should set this property before adding the item to a bar. The default value is nil.
https://developer.apple.com/documentation/uikit/uibaritem/1616412-title

This changes allows for this to be `nil`.

Update Installing.md

Add step 2b that references Header Search Paths that were seen in this GitHub issue:
https://github.com/wix/react-native-navigation/issues/1933

V1 had two SideMenu implementations. In v2 we've decided to stick with one and for some reason
code related to the unsupported implementation was left in the project.

This approach is still not ideal as it assumes there's a visible stack somewhere in the Hierarchy.
It's better than the current implementation so I'm pushing it and will reiterate in the future if needed.

This effectively reverts 96661e3308 and fixes the issue properly.
