Ok I will attempt to port this over instead of the other library. I will first read and understand the BIP174 spec before attempting to do so. I will be posting all my findings here in this thread.

Hi @RohanKapurDEV did you have any status on PBST support ?

I would like to use it to build a transaction for sending to a lightning node - I did look at bitcoin js lib and it seems to support it - but I have decided to go down the path of Flutter for a mobile app rather than react native :-)

Thanks.

I'll take a look and implement it this from this week.

Great thank you.

We can probably use BDK library to build out psbt functionality via ffi:

I would like to work with someone on this.

Either by implementing BIP174 in dart OR using bdk ffi.

We have been working on this project which uses https://github.com/i5hi/stackmate-core.

It is a subset of bdk descriptor wallet tools that together fulufil our use and exposed it to dart via a C ffi.

The bdk team is working on exposing the entire library api here: https://github.com/bitcoindevkit/bdk-ffi

They helped us a lot through building this, but they dont have the resources to prioritize dart for a direct api. If anyone here is interested in taking that up, you should get in touch with them. They have an awesome small team working on ffi bindings.
