Build fails: IntoIntoDart<_> is not implemented

Hi! I'm looking to use this template to develop an app, and tried just running it after cloning (made sure I have what's listed in the README installed). I ran flutter run and see the following error:

   Compiling native v0.1.0 (/home/apm/Documents/flutter_rust_bridge_template/native)
error[E0277]: the trait bound `api::Platform: IntoIntoDart<_>` is not satisfied
  --> src/bridge_generated.rs:25:33

   = help: the following other types implement trait `IntoIntoDart<D>`:

             <DartCObject as IntoIntoDart<DartCObject>>

           and 22 others

Just to make sure, I ran the command suggested by cargo_ndk:

[apm@apg ~/Documents/flutter_rust_bridge_template]$ rustup target install armv7-linux-androideabi
info: component 'rust-std' for target 'armv7-linux-androideabi' is up to date
