How to customize the accessory height?

Issue Description

I’d like to develop an app like wechat:

I tried to custom the accessory height like this:

<GiftedChat
    renderAccessory={()=><View style={{height:300}}/>
/>

But failed.

Steps to Reproduce / Code Snippets

I looked up the lib source code ,and try to change accessoryStyle

<GiftedChat
    renderAccessory={()=><View style={{flex:1}}/>
    accessoryStyle={{height: 300}}
/>

It works, but the accessory has covered the message container.

Expected Results

Custom the accessory height and do not cover the message container.

Additional Information

based on the code in PR #1524 that is not yet merged, you can still extend the original component class both in pure javascript and typescript,

here’s a TypeScript example:

class GiftedChatExtended extends GiftedChat {
  componentDidUpdate(prevProps: GiftedChatProps, prevState: any, snapshot?: any) {
    super.componentDidUpdate && super.componentDidUpdate(prevProps, prevState, snapshot);

    if (prevProps.minInputToolbarHeight !== this.props.minInputToolbarHeight) {
      this.setState({
        messagesContainerHeight: this.prepareMessagesContainerHeight(
          this.getBasicMessagesContainerHeight() - this.getKeyboardHeight()
        ),
      });
    }
  }
}

and then use GiftedChatExtended however you’d use original GiftedChat component

This seems to do the job renderInputToolbar={(props) => { return <InputToolbar {...props} accessoryStyle={{ height: showAcc ? 44 : 0 }} />; }}
