My generated dart file is getting errors like missing_const_final_var_or_type and implicit_this_reference_in_initializer

Hi!

Copied this example. My pubspec:

dependencies:
  flutter:
    sdk: flutter
  ffi: ^1.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter
  ffigen: 4.1.3

ffigen:
  name: NativeLibrary
  description: Bindings to `headers/example.h`.
  output: 'lib/generated_bindings.dart'
  headers:
    entry-points:
      - 'rust/bindings.h'

My header is only 1 row and is: void start_application(void);.
So when I run flutter pub run ffigen it creates a dart file with errors like: Variables must be declared using the keywords 'const', 'final', 'var' or a type name. Try adding the name of the type of the variable or the keyword 'var'. and then The instance member '_start_applicationPtr' can't be accessed in an initializer. Try replacing the reference to the instance member with a different expression

Any clue why I get these errors?

Same here, have you found an answer to this issue ?

Yes. I had to increase the sdk version requirement in my pubspec. sdk: ">=2.16.1 <3.0.0"
