support for IndexMap or custom encoder/decoder for generic types

[uditrugman]

Is there a way to use custom Encoder/Decoder for IndexMap or in general to add custom encoder/decoder for Generic Types?

Thanks

Generics have not been supported yet. A quick method may be to define Rust macros, such that you can easily generate arbitrary generic types.

Is there a way to add custom encode/decode for a specific generic type?

for example IndexMap\<String, usize>

I tried that already but for some reason it ignores my encode/decode functions and generate a new dart type. is there an example of how to use Encode/Decode for a generic with specific type?

Hmm then looks like it is not implemented yet. A quick workaround is to use the newtype pattern, for example:

pub struct MyIndexMapStringUsize(IndexMap<String, usize>);

and then do custom encode/decode on it.

As usual, this can be done via a macro to avoid repeating the code.
