How to change BottomNavigationBar item's color on Flutter?

Question

I've inserted custom icons into my application and when I run the app, the icons and text are white, instead of the original color.

Two Problems:

1)The Icons are originally black but when I insert it to my Bottom Nav Items they become white.

2)Also only the first item has a tittle beneath the icon the rest doesn't.

This is my code

      bottomNavigationBar: BottomNavigationBar(
      items: <BottomNavigationBarItem>[
        BottomNavigationBarItem(
          icon: Icon(const IconData(0xe903, fontFamily: 'navBar')),
          title: Text('Home'),
        ),
        BottomNavigationBarItem(
          icon: Icon(const IconData(0xe902, fontFamily: 'navBar')),
          title: Text('Ideas')
        ),
        BottomNavigationBarItem(
          icon: Icon(const IconData(0xe903, fontFamily: 'navBar')),
          title: Text('Profile')
        ),
        BottomNavigationBarItem(
            icon: Icon(const IconData(0xe901, fontFamily: 'navBar')),
            title: Text('Bag')
        ),

      ],
  ),

//pubspec.yaml file

  fonts:
- family: navBar
  fonts:
    - asset: assets/fonts/ic_navbar.ttf

The 4 icons

You need to add a type for your ButtomNavigationBar

    bottomNavigationBar: BottomNavigationBar(

        //Add this line will fix the issue.
        type: BottomNavigationBarType.fixed,

        currentIndex: 0, // this will be set when a new tab is tapped
        items: <BottomNavigationBarItem>[
          BottomNavigationBarItem(
            icon: new Icon(const IconData(0xe903, fontFamily: 'navBar')),
            title: new Text('Home'),
          ),
          BottomNavigationBarItem(
            icon: Icon(const IconData(0xe902, fontFamily: 'navBar')),
            title: new Text('Messages'),
          ),
          BottomNavigationBarItem(
              icon: Icon(const IconData(0xe903, fontFamily: 'navBar')),
              title: Text('Profile'),
          ),
          BottomNavigationBarItem(
              icon: Icon(const IconData(0xe901, fontFamily: 'navBar')),
              title: Text('Bag')
          ),

        ],

      ),
