danschultz/browser_detect.dart

A Dart package that provides information about the user's web browser.

Browser Detect

A package that detects the browser being used to view a web page. Useful for blanket browser detection. If possible, try to use feature detection over this approach.

Usage

Import the Browser Detect package.

import 'package:browser_detect/browser_detect.dart';

Use the library's browser field to query for information about the detected browser. This field contains properties for checking the browser type and version.

if (browser.isIe && browser.version <= "9") {
  // Do something.
}

browser_detect.dart's Issues

Consider using lazy initialization for the browser variable

Maybe something like this:

final Browser browser = _computeBrowser();
Browser _computeBrowser() {
...
}

See http://news.dartlang.org/2012/02/static-variables-no-longer-have-to-be.html for more details.

Opera is detected as Chrome

browser.isChrome returned true and browser.isOpera returned false for Opera 43.0

IE 11

Thank you for your perfect package! It has only one bug:
It could not detect IE 11. I tried it on a lot of devices with Microsoft Windows 7/8/8.1, but with no success. Could you please fix it? I don't know if this bug is caused by changing the user agent string and other navigator values in IE 11 (now it isn't MSIE, but only IE and sometimes only "Trident/7.0 rv:11.0" - but I don't know it exactly) or if the bug is caused by moving Dart to stable version 1.0 (probably not, but it should be inspected too). Please repair it.

Browser detect simply fails on Chrome on iOS

This is the code in src/browser.dart:

  BrowserVersion get version {
    if (_version == null) {
      var value = _versionMatchers.map((matcher) => matcher())
          // vvvv This is the offending line vvvv
          .firstWhere((match) => match != null)
          .group(1);
      _version = new BrowserVersion(value);
    }
    return _version;
  }

If no match is found, then this simply throws

Detect platform

It would be useful to support detecting the operating system and version with getters such as os, osVersion, isWindows, isLinux, isIOS.

This would likely involve browser sniffing, but perhaps with a growing Dart community the detection rules can be kept up-to-date to provide decent coverage?

Is the actual state ready to make a new version and add it to the pub?

Because the 0.1.0+2 version is really old compilation of the code and the actual state changed a little I think.

Rename src/browesr_version.dart to src/browser_version.dart

Add support for mobile detection

It'd be nice if you could add support for detection of mobile devices. So far I've been using mobile-detect.js.
