and this is the dart file that supposed to convert the.tff file to IconData (alot of icons are included)

import 'package:flutter/widgets.dart';

class IconBroken {
  IconBroken._();

  static const String _fontFamily = 'IconBroken';

  static const IconData User = IconData(0xe900, fontFamily: _fontFamily);
  static const IconData User1 = IconData(0xe901, fontFamily: _fontFamily);
  static const IconData Activity = IconData(0xe902, fontFamily: _fontFamily);
  static const IconData Add_User = IconData(0xe903, fontFamily: _fontFamily);
  static const IconData Arrow___Down_2 = IconData(0xe904, fontFamily: _fontFamily);
  static const IconData Arrow___Down_3 = IconData(0xe905, fontFamily: _fontFamily);
  static const IconData Arrow___Down_Circle = IconData(0xe906, fontFamily: _fontFamily);
  static const IconData Arrow___Down_Square = IconData(0xe907, fontFamily: _fontFamily);
  static const IconData Arrow___Down = IconData(0xe908, fontFamily: _fontFamily);
  static const IconData Arrow___Left_2 = IconData(0xe909, fontFamily: _fontFamily);
  static const IconData Arrow___Left_3 = IconData(0xe90a, fontFamily: _fontFamily);
  static const IconData Arrow___Left_Circle = IconData(0xe90b, fontFamily: _fontFamily);

This is an example of Flutter doc about how to add a custom font. Compare to your file, the spacing is wrong, please take care of the space.

flutter:
  fonts:
    - family: Raleway
      fonts:
        - asset: fonts/Raleway-Regular.ttf
        - asset: fonts/Raleway-Italic.ttf
          style: italic
    - family: RobotoMono
      fonts:
        - asset: fonts/RobotoMono-Regular.ttf
        - asset: fonts/RobotoMono-Bold.ttf
          weight: 700
