Answer 1

Try changing the primary color in your theme or the cursorColor in the theme or TextField

import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';

MaterialApp(
  title: "Rate your Colleagues",
  theme: ThemeData(
    // for iOS
    cupertinoOverrideTheme: CupertinoThemeData(
      primaryColor: Colors.red,
    ),
    // for others(Android, Fuchsia)
    cursorColor: Colors.red,
    home: SplashScreen(),
  );
  ...

Or

new MaterialApp(
  title: "Flutter App",
  theme: ThemeData(
    cursorColor: Colors.red,
    home: HomeScreen(),
)
