我想知道如何只运行一次Lottie动画，因为默认情况下它是循环的。 以下是我要修改的代码的链接：https://docs.expo.io/versions/latest/sdk/lottie.html
感谢。

您可以使用loop prop来设置组件的循环行为。有关您可以使用lottie的属性的更多信息，请访问here。
// A boolean flag indicating whether or not the animation should loop.
loop: boolean = false,

在Java中，禁用像这样的Lottie动画循环可能对此有所帮助：
首先，声明LottieAnimationView： "dependencies": {
"@angular/animations": "5.2.11",
"@angular/cdk": "^5.1.0",
"@angular/common": "5.2.11",
"@angular/compiler": "5.2.11",
"@angular/compiler-cli": "5.2.11",
"@angular/core": "5.2.11",
"@angular/fire": "^5.2.1",
"@angular/flex-layout": "^5.0.0-beta.15",
"@angular/forms": "5.2.11",
"@angular/http": "5.2.11",
"@angular/platform-browser": "5.2.11",
"@angular/platform-browser-dynamic": "5.2.11",
"@ionic-native/core": "~4.11.0",
"@ionic-native/splash-screen": "~4.11.0",
"@ionic-native/status-bar": "~4.11.0",
"@ionic/pro": "^2.0.3",
"@ionic/storage": "^2.2.0",
"@ngrx/effects": "^5.2.0",
"@ngrx/store": "^5.2.0",
"@ngrx/store-devtools": "^5.2.0",
"@types/cordova": "0.0.34",
"cordova-android": "^7.1.4",
"cordova-browser": "^5.0.4",
"cordova-ios": "^4.5.5",
"cordova-plugin-device": "^2.0.2",
"cordova-plugin-file": "^6.0.1",
"cordova-plugin-file-transfer": "^1.7.1",
"cordova-plugin-ionic": "^5.3.1",
"cordova-plugin-ionic-keyboard": "^2.1.3",
"cordova-plugin-ionic-webview": "^2.5.1",
"cordova-plugin-splashscreen": "^5.0.2",
"cordova-plugin-statusbar": "^2.4.2",
"cordova-plugin-whitelist": "^1.3.3",
"firebase": "^6.2.4",
"ionic-angular": "3.9.2",
"ionic2-auto-complete": "^1.6.2-alpha",
"ionicons": "3.0.0",
"ng2-nvd3": "^2.0.0",
"ngx-perfect-scrollbar": "^5.3.5",
"rxjs": "6.2.0",
"rxjs-compat": "6.2.0",
"sw-toolbox": "3.6.0",
"zone.js": "0.8.26"
},
然后找到ID为LottieAnimationView myAnim; // //在这里查看v，因为它是片段工作，所以我使用它。
现在您可以使用布尔值更改循环选项：myAnim = v.findViewById(R.id.upload_anim);

在 flutter 中，只需在资产后执行 repeat:false
像这样：
Lottie.asset('assets/lottie.json',repeat: false)
