Title, Confirm and Cancel in Dark mode is not visible

[theDevSoham]

Describe the bug
Only tested on android: The dark mode text for the calendar is not changing color with theme change.

Expected behavior
To be set to white when in dark mode or preferably should take a customizalbe React.Fragment instead of a string

To Reproduce
Add example code that reproduces the behavior.

export default class App extends Component {

  state = { date: new Date() }

  render = () =>
    <DatePicker
                modal
                open={true}
                date={state }
                onConfirm={(d) => {
                  console.log("Date changed: ", d)
                }}
                onCancel={() => {
                  console.log("Cancelled: ")
                }}
                theme="dark"
                title="Select Date"
              />

}

Same issue here

[cyrilmarceau]

Same issue but only on google device. I have tested on a samsung s10e and problem will not appear

We've had to work around this by using theme="light" but it would be great to get this fixed.

[theDevSoham]

theme="light" actually works fine...there's only some issue with dark mode heading and bottom buttons. It really needs some fix.

This same issue exists for me with the date picker fields. This can be seen in #734

[mkhoussid]

Is there a planned fix or we might as well fork this repo and do it ourselves?
