eslint-plugin-flowtype 函数调用 入参不对时没有生效？

Question

flow.js

//@flow

function test(n: number): number {
    return n * n;
}

function test2(n) {
    return n * n;
}



test('9');

export default {
    desc: 'flow checker',
    square(n: number): number {
        return n * n;
    }
};

我的配置文件

.eslintrc.js

    }
}

备注：

采用flow 官网那样 通过flow-bin 检查语法可以提示 test("9") :flow:string this type is incompatible ...

但 我想在vueJs项目中通过eslint 控制 编写规范，然后在webpack 打包时，eslint-loader控制有错误则终止编译。所以官网那样 的 提示不符合我的需求。

eslint-plugin-flowtype 这个lint检查的rules是flow的语法检查，并不是像flow check那样检查类型，只会检查你写的flow注释规不规范这样
