SEMANTIC ANALYSIS

ⓘ The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by flutter.io.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics

Free and open-source software Confidence: 79%

Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software. That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users.

Mobile Web Confidence: 76%

The mobile Web refers to browser-based Internet services accessed from handheld mobile devices, such as smartphones or feature phones, through a mobile or other wireless network.

Google Confidence: 76%

Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, software, and hardware.

Application software Confidence: 73%

An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor. The collective noun application software refers to all applications collectively. This contrasts with system software, which is mainly involved with running the computer.

Codebase Confidence: 72%

In software development, a codebase (or code base) refers to a whole collection of source code that is used to build a particular software system, application, or software component. Typically, a codebase includes only human-written source code files; thus, a codebase usually does not include source code files generated by tools (generated files) or binary library files (object files), as they can be built from the human-written source code. However, it generally does include configuration and property files, as they are the data necessary for the build.
