getCurrentRoutes api in v4?

[ghost]

how can i get all route in current route stack in v4? i find some talk about Actions.currentRouter, but i cannot find about currentRouter code in v4 source code.

Ah crap I thought I had a code example for this, digging around still...

Can you try setting up a reducer:

const reducerCreate = params => {
  const defaultReducer = new Reducer(params);
  return (state, action) => {
    console.log('ACTION:', action);
    return defaultReducer(state, action);
  };
};

Attach it like so:

      <Router
        ...
        createReducer={reducerCreate}
      >

Now you can console.log(state) in the function and move around its tree, I think what you are looking for is in there IIRC

Looking through the source it doesn't look like currentRouter exists anymore (there IS a currentScene), I'd be curious what you need it for to maybe guide you to an alternate solution?

i use react native's own navigator now(version 0.39), it has a api called getcurrentroutes, this can get a list include all pushed routes, and i cannot found a similar api in rnrf.

Actions.state

@fatfatson is correct.

But Can i get the Stack size?

@matteocollina have you looked at the state object as pointed above? you can get the idea of the stack size by that.

This is a sample that I got by running the tests from the project:

{
  "key": "StackRouterRoot",
  "isTransitioning": false,
  "index": 0,
  "routes": [
    {
      "key": "id-1537858201424-3",
      "isTransitioning": true,
      "index": 1,
      "routes": [
        {
          "params": {
            "init": true,
            "param": "1"
          },
          "routeName": "a",
          "key": "id-1537858201424-2"
        },
        {
          "params": {
            "error": "",
            "param": "2",
            "init": true,
            "data": "abcde",
            "routeName": "c"
          },
          "routeName": "c",
          "key": "id-1537858201424-4"
        }
      ],
      "params": {
        "init": true
      },
      "routeName": "b"
    }
  ]
}
