Flutter: Unable to load text assets

Question

My file endpoints.json is in /WORKPLACE_DIR/assets/json/endpoints.json

{
  "key": "value"
}

I have updated my pubspec.yaml

assets:
    - assets/json/endpoints.json

In /tests/some_test.dart

I do

test('my test', () async {
      final endpoints = json.decode(await rootBundle.loadString("assets/json/endpoints.json"));
    }

It still gives an error

ERROR: Unable to load asset: assets/json/endpoints.json

package:flutter/src/services/asset_bundle.dart 67:33  AssetBundle.loadString

I have tried flutter clean but it still gives this error. I am not sure what to do.

I had similar problem with images. The reason was simple, I skipped the tab before "assets:". If the words "flutter:" and "assets:" are on the same level in your pubspec.yaml file you will get the "unable to load asset" error. So just add the tab before "assets:" and "- assets/json/endpoints.json".
