Key Concepts

核心概念

Package:
```
flutter pub add nutrient_flutter
```
. The legacy
```
pspdfkit_flutter
```
package is the pre-rebrand name; new projects use
```
nutrient_flutter
```
.
Main widget:
```
NutrientView
```
— embeds the PDF viewer inline. Use
```
NutrientInstantView
```
instead when you need real-time collaborative annotation via Nutrient Instant. The legacy
```
PspdfkitWidget
```
is the pre-rebrand name.
Required initialisation: call
```
Nutrient.initialize(androidLicenseKey: ..., iosLicenseKey: ...)
```
in
```
main()
```
before
```
runApp()
```
. The SDK refuses to work without
```
initialize()
```
having been called — this requirement is new in the Nutrient era; the legacy
```
pspdfkit_flutter
```
plugin auto-initialised.

包：

flutter pub add nutrient_flutter

。旧版

pspdfkit_flutter

包是更名前的名称；新项目请使用

nutrient_flutter

。

主组件：
```
NutrientView
```
—— 用于内嵌PDF查看器。如果需要通过Nutrient Instant实现实时协作批注，请改用
```
NutrientInstantView
```
。旧版
```
PspdfkitWidget
```
是更名前的名称。
必填初始化：在
```
runApp()
```
之前，于
```
main()
```
中调用
```
Nutrient.initialize(androidLicenseKey: ..., iosLicenseKey: ...)
```
。未调用
```
initialize()
```
的情况下SDK无法正常工作——这是Nutrient时代新增的要求；旧版
```
pspdfkit_flutter
```
插件会自动初始化。
