Enable dynamic sliding tabs

[gwmccull]

This project builds off of #337 (since it edits the same file, I didn't want to worry about conflicts down the road).

It allows the user to update the list of tabs in their app and have the change reflected in the horizontal tabs

Here's an example of the code from the render function in my app:

<SlidingTabNavigation
	id="sliding-tab-navigation"
	navigatorUID="sliding-tab-navigation"
	initialTab="shop"
	renderLabel={this.renderLabel}
	barBackgroundColor="#fff"
	indicatorStyle={componentStyles.tabIndicator}
	tabBarScrollEnabled={true}
>
	{
		this.state.tabs.map((tab) => {
			return (
				<SlidingTabNavigationItem
					id={tab.id}
					key={tab.id}
				>
					{tab.component()}
				</SlidingTabNavigationItem>
			);
		})
	}
</SlidingTabNavigation>

Later, the app can just update the state with a new set of tabs and the change will be reflected in the UI.

Hey! Thanks for the PR. Please take a look at https://github.com/exponent/ex-navigation#an-important-note-about-the-future

[gwmccull]

@satya164 thanks. Any idea if these issues will already be resolved in the new repo?

I have a nav project that needs to begin immediately and will probably be wrapping up near the end of the month

Thanks

@gwmccull Currently dynamic tabs are not possible in React Navigation. But we're actively exploring ideas.

[satya164]

@gwmccull For your project you can directly use https://github.com/satya164/react-native-tab-view for now.

@satya164 good to know. We're planning to migrate once the new lib comes out.

Sounds like we may need to plan extra time to roll our own dynamic tab system :-)

Hopefully it won't take much time. All the best!

@satya164 I'm working with a great team of React Native developers and we're pretty excited to work with the new navigation lib.

Do you know if things are getting to the point where outside groups could contribute to its development?

[satya164]

@gwmccull I think we're pretty close. Keep an eye out for the announcement :D

[gwmccull]

@satya164 that's great! Have a good weekend

Where will an announcement about the new lib be made? Is there any way to follow along with what's happening?
