Step 4: Provide the child inside the child parameter.

Step 5: Run the app.

Code Example

ElevatedButton(
  onPressed: () => _selectDate(context),
  child: const Text(
    'Show Date Picker',
    style: TextStyle(fontSize: 24),
  ),
),
//------
_selectDate(BuildContext context) async {
  final DateTime? selected = await showDatePicker(
    context: context,
    initialDate: DateTime.now(),
    firstDate: DateTime(2010),
    lastDate: DateTime(2025),
    builder: (context, child) {
      return Theme(
        data: Theme.of(context).copyWith(
          colorScheme: ColorScheme.light(
            primary: Colors.amberAccent, // <-- SEE HERE
            onPrimary: Colors.redAccent, // <-- SEE HERE
            onSurface: Colors.blueAccent, // <-- SEE HERE
          ),
          textButtonTheme: TextButtonThemeData(
            style: TextButton.styleFrom(
              primary: Colors.red, // button text color
            ),
