Typer

  hintTextStyle: const TextStyle(
    color: Colors.deepPurple,
    overflow: TextOverflow.ellipsis,
  ),
  hintTexts: const [
    'How is the weather today?',
    'Will it rain today?',
    'What is the temperature',
  ],
  decoration: InputDecoration(
    suffixIcon: const Icon(Icons.search),
    filled: true,
    border: OutlineInputBorder(
      borderSide: const BorderSide(color: Colors.red, width: 2),
      borderRadius: BorderRadius.circular(25),
    ),
    focusedBorder: OutlineInputBorder(
      borderSide: const BorderSide(color: Colors.black, width: 2),
      borderRadius: BorderRadius.circular(25),
    ),
    contentPadding: const EdgeInsets.all(12),
  ),
);

💡 Tip

Use staticHintText when part of the hint should stay fixed while only the animated part changes:

AnimatedTextField(
  staticHintText: 'Search for ',
  hintTexts: const ['Bengaluru', 'Mumbai', 'Chennai'],
);

For suffix-style hints, set staticHintTextPosition:

AnimatedTextField(
  staticHintText: ' nearby',
  staticHintTextPosition: StaticHintTextPosition.suffix,
  hintTexts: const ['Cafe', 'Hotel', 'Restaurant'],
);

By default, the animated hint text can span multiple lines if the text is long. If you want to keep the hint on a single line and show overflow with ellipses (...), set the overflow property in hintTextStyle:

hintTextStyle: TextStyle(
  overflow: TextOverflow.ellipsis,
),
