Which do you think is the best way to face a mobile MVP?

I'm in the experimentation phase so I want to validate an idea and for that, I need an environment in which I can do fast changes. At the same time if after some iterations the idea has some traction I would like to be in a position in which I can distribute it easily between the different markets.

I received different advice about it:

• Flutter
• Native
• PWA
• React native
• Unity

It's a very basic mobile application in which the user will handle a list of data he will populate.

Thanks for any advice in advance!
