version: 1.0.0+1

The version of your application or package.

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0"

Your application or package claims to support Dart SDK within this version range

dependencies:
  flutter:
    sdk: flutter

Your application or package depends on the flutter package which can be found in the SDK

  sqflite: any

Your application or package depends on the package sqflite from https://pub.dartlang.org with no specific version constraint.

  path_provider: any
  intl: ^0.15.7

Your application or package depends on the package intl from https://pub.dartlang.org on any version 0.15.7 or later but before 0.16.0.

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

The ^ changes the meaning for versions 1.0.0 and later.

^0.15.7 means >=0.15.7 <0.16.0 ^1.15.7 means >=1.15.7 <2.0.0

because for versions < 1.0.0 breaking changes are indicated by incrementing the middle number, while for >= 1.0.0 breaking changes are indicated by incrementing the first part of the version.

It is responsible for handling of importing images/fonts/third party packages which you want to include in your project.

As explained here on the Flutter site:

The pubspec file manages the assets and dependencies for a Flutter app.

More info can be found here.

To briefly explain, this file written in the YAML language, allows you to manage the pub packages you want to use in your flutter app.

From the dart page :

Every pub package needs some metadata so it can specify its dependencies. Pub packages that are shared with others also need to provide some other information so users can discover them. All of this metadata goes in the package’s pubspec: a file named pubspec.yaml that’s written in the YAML language.

So you will find all the required dependencies / fonts and images sources /sdk version in the pubspec.yaml
