Wrong line error

[vonovak]

thanks for the plugin!

I encountered this when editing the last line of file. I probably made a new line before the error appeared.

Thank you for the report!

Do you remember more details of the scenario that led to this, and can you reproduce it consistently? I'm having a bit of trouble reproducing that exception.

[vonovak]

try this file:

/**
 * @flow
 */
export default class Project {
    id: number;
     status: string;
     name: string;

    constructor(ProjectStore: any, projectJson: Object) {
        this.id = projectJson.id;
        this.status = projectJson.status
    }

}

note the empty line at the end.
start writing on the empty line (var for example) and the error should pop out.

Hmm, still can't repro with that file and that webstorm version. What does your project structure look like and what's in your .flowconfig?

[vonovak]

.flowconfig

.*/node_modules/*

[include]

[libs]
node_modules/react-native/Libraries/react-native/react-native-interface.js
node_modules/react-native/flow
flow/

[options]
module.system=haste
esproposal.decorators=ignore
unsafe.enable_getters_and_setters=true

esproposal.class_static_fields=enable
esproposal.class_instance_fields=enable

as for project structure, I have a root folder with node_modules and js subfolder (with a bunch of other subfolders) and then other react native-specific folders

[dsilva]

Thank you -- I can see it now. This happens whenever Flow reports a parse error of the form "Unexpected end of input" and is similar to the issue another plugin ran into at mrcljx/rubocop-for-rubymine#17
