changing fonts in flutter code example

Example 1: flutter font bold

Text(
  'Some text',
  style: TextStyle(
    fontSize: 24,
    fontWeight: FontWeight.bold),
)

Example 2: flutter add custom fonts

flutter:
  fonts:
    - family: Proxima
      fonts:
        - asset: lib/fonts/ProximaNova-Regular.otf

In case you are using an emulator, go to the terminal and type "flutter clean" then "flutter pub get" to update the font used.
