Question

朋友们你好，我正在学习在 Flutter 中构建应用程序。我在 Flutter 中创建了一个应用程序，我想在我的代码中正确实现 SingleChildScrollView。我怎么能这样做？有什么帮助吗？先谢谢各位朋友

我的代码：

sudo: required
language: generic

services:
  - docker

stages:
  - dev
  - prod

jobs:
  include:
    - stage: dev
      if: NOT(branch=master)
      scripts:
        - docker build -t harryyy27/allies_art_club/frontend -f ./client/Dockerfile.dev ./client
        - docker build -t harryyy27/allies_art_club/backend -f ./src/Dockerfile.dev ./src
        - docker run -e CI=true harryyy27/allies_art_club/frontend npm test
        - docker run -e CI=true harryyy27/allies_art_club/backend npm test
    - stage: prod
      if: branch=master
      before_deploy:
        - docker build -t harryyy27/aac-client ./client
        - docker tag harryyy27/aac-client registry.heroku.com/$HEROKU_APP/client
        - docker build -t harryyy27/aac-src ./src
        - docker tag harryyy27/aac-src registry.heroku.com/$HEROKU_APP/src
        - docker build -t harryyy27/aac-nginx ./nginx
        - docker tag harryyy27/aac-nginx registry.heroku.com/$HEROKU_APP/nginx
      # Log in to docker CLI
        - echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_ID" --password-stdin
        - curl https://cli-assets.heroku.com/install.sh | sh
        - echo "$HEROKU_API_KEY" | docker login -u "$HEROKU_USERNAME" --password-stdin registry.heroku.com
        - docker push harryyy27/aac-client;
        - docker push registry.heroku.com/$HEROKU_APP/client;
        - docker push harryyy27/aac-src;
        - docker push registry.heroku.com/$HEROKU_APP/src;
        - docker push harryyy27/aac-nginx;
        - docker push registry.heroku.com/$HEROKU_APP/nginx;
      deploy:
        skip_cleanup: true
        provider: script
        script:
          heroku container:login;
          heroku container:release client src nginx --app $HEROKU_APP;

Answer 2

你能试试这个代码吗

CustomScrollView(
            scrollDirection: Axis.vertical,
            slivers: [
              SliverFillRemaining(
                hasScrollBody: false,
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                  children: [
                    Text('everything works'),
                    for (int i = 0; i < 10; i++) const FlutterLogo(size: 80)
                  ],
                ),
              ),
            ],
          ),
