withRouter, connect() and react-compose

I am using react-redux connect function with withRouter function, and also I am trying to use compose() here. This is the code:

export default compose (
    withRouter,
    connect(mapStateToProps)
)(Dashboard);

But I receive the next error:

export default withRouter(connect(mapStateToProps)(Dashboard))

Works fine and is short.

You can simply use this as mentioned by Parnab Sanya

export default withRouter(connect(mapStateToProps)(HomeComponent))

or If you have withStyles() then use this

export default withRouter(
compose(
   withStyles(HomeComponentStyle),

   connect(mapStateToProps)
)(HomeComponent));

connect returns a function that takes the component. So, I think it would work if you slightly change your parens:

export default compose(
    withRouter,
    connect(mapStateToProps)(Dashboard)
);

Or:

export default connect(mapStateToProps)(compose(
    withRouter,
    Dashboard
));
