The Dart String Endswith method
The dart endsWith() is used to check if a string ends with a given(another) String value. Examples void main() { String givenString = "This MAy LoOk aWkwaRd"; print(givenString.endsWith("d")); } The above function will print true.

Convert String to Lower Case and Upper Case in Dart
The Dart language has simple ways to change the cases of Strings. To convert a given string to lower case, we can use the toLowerCase() method. It will convert all the characters in the given string to lower case. String givenString = "This MAy LoOk aWkwaRd"; var resultantString = givenString.toLowerCase(); // print(resultantString); // "this may look awkward" The above code will print this may look awkward to the console. Similarly, To convert a given string to upper case, we can use the toUpperCase method.

The Dart String Trim method
The Dart trim() method returns the given String after removing whitespaces at the beginning and end of the String. Examples " SampleText".trim() // "SampleText" "SampleText ".trim() // "SampleText" " SampleText ".trim() // "SampleText" "SampleText".trim() // "SampleText" Note that, this will not remove whitespace in the middle of a sentence.

There is no need for a huge story here. Deleting a Firestore document is a straightforward thing. We just have to point to a doc and call delete on it. final _db = FirebaseFirestore.instance; await _db.collection("notes").doc("note1").delete(); That’s it. The pointed document will be deleted by the above function.
