Is Dhan built using Flutter or React Native?

How is Dhan app built? Using Flutter or React Native or Java/Kotlin for Android, Swift for iOS? Being a developer myself, very interested to know the stack being used. Also, on which framework is Dhan website ( built?

Our tech stack are a bit mix of all at this moment. Maybe at some point in future when tested for all the components for speed, scale and reliability we will start posting more about what we are using.

At this stage, very very early in our journey.
