Flutter 如何使PageView.builder填充整个屏幕大小

我不知道怎么做，我只知道这个

有人能帮我吗？我需要得到这个

尝试从代码中删除SafeArea，如下所示：-

return SizedBox(
    width: double.infinity,
    height: double.infinity,
    child: Scaffold(
      body: PageView.builder(
        scrollDirection: Axis.horizontal,
        itemCount: _model.length,
        itemBuilder: ( context, index ) => OnboardingContent(
          image: _model[index].image,
          text: _model[index].title,
          text2: _model[index].subtitle,
        ),
      )
    ),
);

您还需要显示登录内容代码以进行评估

return SizedBox(
    width: double.infinity,
    height: double.infinity,
    child: Scaffold(
      body: PageView.builder(
        scrollDirection: Axis.horizontal,
        itemCount: _model.length,
        itemBuilder: ( context, index ) => OnboardingContent(
          image: _model[index].image,
          text: _model[index].title,
          text2: _model[index].subtitle,
        ),
      )
    ),
);
