There have been several iterations to have a unified way to build Android and iOS apps.

  - using HTML
  - using JavaScript
  - using JS+React
  - using Dart
  - using Kotlin
  - using Swift

This fundamentally does not work for anyone with more than 10M+ installs just like you can't write Mandarin and English in one script.

This only works for devs who over time churn out as their app fails or becomes too big [1]
