flutter astprint

[fangkyi03]

Hello, I'm very glad to find your astprint article in github.

But this demo just outputs AST

How do I process the ast returned from this output?

What about the output of the revised values?

There are many articles on babel, but I haven't found one yet.

I hope I can get your help very much.

Hi @fangkyi03, thanks for your interest in astprinter!

This is currently a command line tool which works with files. It will take a file in, and it will output AST as a string. You can't use it programmatically as a library.

However, it won't be hard to make it into a library, I'd be interested in doing that. Would you mind sharing how you'd like to ideally use it? What sort of features are important to you?

Thanks

Hello, I actually have an idea that I want to convert flutter code into ts.

It also supports converting TS code into flutter

After all, the code in the flutter section is really too verbose.

I want to write flutter in a react-like way

This is great! I've long been wishing flutter was more react-like.

So astprinter may not be that useful to you in this case, as all it does is output the entire AST as a string. This is usually helpful to have as a reference while developing a transformer that acts on the actual AST with its type information intact.

Take a look at how this package uses the analyzer to parse and traverse a file's AST. Here's an example that transforms JSX (DSX) to regular Flutter code https://spark-heroku-dsx.herokuapp.com/index.html

At present, the biggest problem is that flutter is imported through package.

This is completely different from ts or JS

So the d.ts file cannot be generated if TS is used for editing.

So I would like to write a script like Babel that converts all flutter code into ts.

This facilitates writing and completes the effect in this way.

I found a way to write react directly in dart and use Babel or TS directly without using flutter's AST transformation.
