HtmlEditor class

HTML file injection helper for CLI commands.

Provides pure string-based utilities for reading and modifying HTML files (e.g. web/index.html) without external parser packages.

Usage

// Read raw HTML
final html = HtmlEditor.read('/path/to/index.html');

// Inject a script tag before </head> (guard with hasContent first)
if (!HtmlEditor.hasContent('/path/to/index.html', 'OneSignalSDK')) {
  HtmlEditor.injectBeforeClose(
    '/path/to/index.html',
    '</head>',
    '  <script src="sdk.js" defer></script>',
  );
}

// Add a <meta> tag (idempotent)
HtmlEditor.addMetaTag('/path/to/index.html', {
  'name': 'description',
  'content': 'My Flutter App',
});
