A function for capitalization of first letter

  String capitalizeOnlyFirstLater() {
    if(this.trim().isEmpty) return "";

    return "${this[0].toUpperCase()}${this.substring(1)}";
  }

Then call the function in text

Text("${_products[index]["product_name"].capitalizeOnlyFirstLater()}",style: TextStyle(fontSize: 22.sp,),)

You can get the first letter and convert it to uppercase and concatenate the rest with it.

final String productName = _products[index]["product_name"];
final String productNameInSentenceCase = productName[0] + productName.substring(1);

Text(productNameInSentenceCase, style: TextStyle(fontSize: 22.sp,),)
