While Flutter uses a Widget-based interface, React Native is Component-based to support Native UI features of iOS and Android. This makes Flutter compilation Ahead of Time and React Native Compilation Just in Time. Here’s a table comparing Flutter vs React Native, two popular frameworks...

点击ComponentElement.mount。你现在就在Textelemnt里了。Component element(比如StatelessElement)不会直接创建render object,但是他们会创建其他的element,让这些elemnt去创建render object。 下面就是几个调用栈的方法了。点击ComponentElement.performRebuild。找到built = build()那一行。这里,同学们,就是Textwidget的build...
