xlyasdasd commented 3 years ago

Steps to Reproduce

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.business_basketball_flutter_main)
    for (i in 0 until 2) {
        val fragment = FlutterFragment.withNewEngine().url("flutter://basketball/test/login").build<FlutterFragment>()
        mFragments.add(fragment)
    }
    mFragPagerAdapter = MyFragPagerAdapter(supportFragmentManager, mFragments)
    viewPager.adapter = mFragPagerAdapter
    mFragPagerAdapter.notifyDataSetChanged()
}

private class MyFragPagerAdapter(fm: FragmentManager?, private val fragments: List<Fragment>) : FragmentPagerAdapter(fm) {
    override fun getItem(position: Int): Fragment {
        return fragments[position]
    }

    override fun getCount(): Int {
        return fragments.size
    }
}

使用上面Demo运行任意Flutter页面
观察发现ViewPager第一个页面显示纯白屏(无Debug标签)，第二个页面正常显示
