The bottom state of the KeyboardAvoidingView component infinitely updates on Android. This is visible when inspecting KeyboardAvoidingView's state in React Native DevTools, it continuously changes value. Or when a component is rendered just above the keyboard, it flickers and/or bounces up and down.
Steps to reproduce
Prerequisites
App from reproducer repo is built and open. Reproduction 1 is on branch example-1. Reproduction 2 is on branch example-2. For each branch, checkout, yarn install then yarn android.
React Native DevTools is running.
Reproduction 1
Reproduction 1 is a text input and footer fixed to the bottom wrapped in a KeyboardAvoidingView. While the bottom state changes, the change is so small (<1 px) that it is not noticeable in the UI.
Steps
Inspect KeyboardAvoidingView in the React Native DevTools.
Focus on text input in app.
Check bottom state in DevTools.
Unfocus text input in app.
Check bottom state in DevTools.
Expected behaviour
The bottom state should not continuously change.
Actual behaviour
The bottom state continuously changes.
Reproduction 2
Reproduction 2 is the same as reproduction 1 but with two screens to show the effect on the UI as the bottom state change is much larger.
Steps
Focus on text input in the app.
Tap "Go to screen 2".
Inspect Screen2's KeyboardAvoidingView in the React Native DevTools.
Expected behaviour
The bottom state should not continuously change. The footer should not be flickering.
Actual behaviour
The bottom state continuously changes. The footer is flickering.
