SolidBottomSheet(
        headerBar: Container(), // Your header here
        body: Container(), // Your body here
      ),

Properties

  // This controls the minimum height of the body. Must be greater or equal of 0.
  // By default is 0
  final double minHeight;

  // This controls the minimum height of the body. By default is 500
  final double maxHeight;

  // This is the content that will be hided of your bottomSheet. You can fit any
  // widget. This parameter is required
  final Widget body;

  // This is the header of your bottomSheet. This widget is the swipeable area
  // where user will interact. This parameter is required
  final Widget headerBar;

  // This flag is used to enable the automatic swipe of the bar. If it's true
  // the bottomSheet will automatically appear or disappear when user stops
  // swiping, but if it's false, it will stay at the last user finger position.
  // By default is true
  final bool autoSwiped;

  // This flag enable that the user can toggle the visibility with just tapping on
  // the header bar. By default is false
  final bool toggleVisibilityOnTap;

  // This flag enable that users can swipe the body and hide or show the
  // solid bottom sheet. Turn on false if you don't want to let the user
  // interact with the solid bottom sheet. By default is false.
  final bool draggableBody;
  
  // This flag enable that users can swipe the header and hide or show the 
  // solid bottom sheet. Turn on false if you don't want to let the user 
  // interact with the solid bottom sheet. By default is true. 
  final bool canUserSwipe;

  // This property defines how 'smooth' or fast will be the animation. Low is
  // the slowest velocity and high is the fastest. By default is medium.
  final Smoothness smoothness;

  // This property is the elevation of the bottomSheet. Must be greater or equal
  // to 0. By default is 0.
  final double elevation;

  // This flag controls if the body is shown to the user by default. If it's
  // true, the body will be shown. If it's false the body will be hided. By
  // default it's false.
  final bool showOnAppear;

  // This object used to control behavior internally
  // from the app and don't depend of user's interaction.
  // can hide and show  methods plus have isOpened variable
  // to check widget visibility on a screen
  final SolidController controller;

  // This method will be executed when the solid bottom sheet is completely
  // opened.
  final Function onShow;

  // This method will be executed when the solid bottom sheet is completely
  // closed.
  final Function onHide;

Controller

  // This is the current smoothness of the bottomSheet
  Smoothness smoothness;

  // Returns the value of the height as stream
  Stream<double> heightStream;

  // Returns the value of the visibility as stream
  Stream<bool> isOpenStream;

  // Returns the value of the height
  double height;

  //  Returns if the solid bottom sheet is opened or not
  bool isOpened;

  // This method sets the value of the height using streams
  void height(double value);

  // Updates the visibility value to false
  void hide();

  // Updates the visibility value to true
  void show();

Posible incoming features

• A Shadow that covers the back of the bottom sheet to feel more native.
• Full view option that displays the bottom sheet like a new navigated page.
• Controller callbacks to execute when show() and hide() methods are invoked.
