How to dynamically resize text in Flutter?

Question

I retrieve a piece of text from an API. I want to allot a set amount of space to it (say a max Container with width: 300.0 and height: 100.0). Sometimes, the piece of text fits

You can do it using the auto_size_text package:

Container(
  child: ConstrainedBox(
    constraints: BoxConstraints(
      minWidth: 300.0,
      maxWidth: 300.0,
      minHeight: 30.0,
      maxHeight: 100.0,
    ),
    child: AutoSizeText(
      "yourText",
      style: TextStyle(fontSize: 30.0),
    ),
  ),
);

You can also set maxLines to constrain the text even further or use presetFontSizes if you only want to allow specific font sizes.
